Top 10 Best Kensington Trackball in 2026 Compared

The comparison below highlights the principal differences among all ten Kensington trackballs, including ball size, connection style, scrolling hardware, customization, and ergonomic design. Use it to identify the model that best matches your desk, hands, and computer setup.

1. Kensington Expert Wireless Trackball – Best Overall Control

4.2Editor scoreCheck price on Amazon

Kensington Expert Wireless Trackball Mouse

55mm Diamond Eye tracking ball

Bluetooth LE and 2.4GHz

Detachable ergonomic wrist rest

Four customizable buttons

The Kensington Expert Wireless Trackball Mouse combines a large 55mm ball with Diamond Eye optical tracking, making it a persuasive all-around choice for users who want precise cursor movement without repeatedly moving their arm. Its 4.2 rating reflects a generally favorable feature set, particularly its connectivity, wrist support, and customizable controls.

Pros

• Large ball supports precise control
• Works with three connection modes
• Removable wrist rest adds comfort
• Cursor and scroll speed controls
• Broad operating-system compatibility

Cons

• Software lacks Windows ARM support
• Larger footprint than compact models

The large ball gives it a deliberate feel that can suit document navigation, spreadsheet work, and detailed on-screen editing. Its patented scroll ring provides a separate mechanism for vertical navigation, while the four-button layout can be adapted through KensingtonKonnect software. The ambidextrous shell and detachable wrist rest further improve its suitability for long work sessions and shared desks.

Connectivity is one of the Expert's strongest features. It can use Bluetooth LE or a 2.4GHz USB dongle, and it includes power-saving and auto-sleep behavior to help preserve battery life. A reasonable trade-off is that the unit occupies more space than the compact Orbit models, and the customization software does not currently support Windows ARM-based computers.

This is the most balanced recommendation for someone who values control, comfort, and flexible connectivity without moving to a rechargeable flagship. Choose it if you regularly switch between a laptop and desktop, use both Bluetooth and USB receivers, or want a trackball with a larger ball and a removable wrist rest.

Precision From a Large Ball

The 55mm ball provides a substantial rolling surface, which can make fine cursor placement and controlled scrolling feel deliberate. Diamond Eye optical tracking is designed to support accurate movement while keeping the device stationary on the desk.

Flexible Wireless Workflows

Bluetooth LE and 2.4GHz wireless support different workstation habits. The USB dongle is especially convenient for systems where wireless pairing could be inconvenient, while Bluetooth can reduce cable clutter on compatible computers.

2. Kensington SlimBlade Pro – Best Premium Customization

4.1Editor scoreCheck price on Amazon

Kensington SlimBlade Pro Wireless Trackball

55mm dual-sensor ball

Rechargeable four-month battery

Three connection options

Eight programmable button sets

The Kensington SlimBlade Pro Wireless Trackball is the feature-rich option in this guide, combining a 55mm ball, dual tracking sensors, a rechargeable battery, and extensive programmable controls. Its 4.1 rating makes it a strong premium choice for power users who want to tailor the device closely to different applications and working styles.

Pros

• Extensive programmable button profiles
• Rechargeable battery reduces interruptions
• Works wired or wirelessly
• Low-profile ambidextrous shape
• Dual sensors aid accurate tracking

Cons

• Premium feature set may be excessive
• Windows ARM systems remain unsupported

We may earn a commission when you buy through this link, at no additional cost to you.

Its most distinguishing feature is support for eight sets of programmable buttons through KensingtonKonnect. Users can assign program functions and create different configurations for work, communication, browsing, and creative tasks. The low-profile body is designed for both right- and left-handed users and requires less arm and wrist movement than a conventional mouse.

The SlimBlade Pro also provides unusually broad connection flexibility. It works through Bluetooth, a 2.4GHz USB-A receiver with a USB-C adapter, or a wired USB-C cable. A single USB-C recharge is stated to deliver up to four months of battery life, which suits users who prefer not to manage disposable batteries.

The main compromise is complexity. Users seeking a basic plug-and-play device may not need eight button sets, dual sensors, or three connection modes. Even so, the feature set makes this a strong candidate for a permanent desk setup, a shared office, or anyone who frequently switches between demanding applications.

Profiles for Power Users

Eight sets of programmable buttons can preserve different workflows without constantly rearranging hardware. This makes the trackball especially useful for people who move between productivity suites, creative software, development tools, and communication platforms.

Rechargeable Three-Mode Connectivity

The rechargeable battery and choice of Bluetooth, 2.4GHz, or wired operation offer several ways to adapt to different computers. Included USB-C charging and adapter cables add flexibility for modern and mixed-device desks.

3. Kensington Orbit Scroll Ring – Best Classic Trackball Feel

4.3Editor scoreCheck price on Amazon

Kensington Orbit Trackball Mouse with Scroll Ring

40mm precision tracking ball

Mechanical scroll ring

Removable cushioned wrist rest

Two programmable buttons

The Kensington Orbit Trackball Mouse with Scroll Ring delivers a traditional trackball experience through optical tracking, a 40mm hard-surface ball, and a tactile scroll ring. Its 4.3 rating is among the strongest in this collection, reflecting a well-established design with precise tracking and useful physical scrolling.

Pros

• Precise hard-surface ball
• Distinct mechanical scroll ring
• Comfortable removable wrist support
• Works for either hand
• Simple cursor speed adjustment

Cons

• Only two programmable buttons
• Wired connection limits portability

We may earn a commission when you buy through this link, at no additional cost to you.

The blue 40mm ball is engineered as an absolute sphere, which supports controlled movement across the desktop. Its mechanical scroll ring moves through web pages and documents with a distinctly tactile action. The detachable wrist rest cushions the hand during extended use, while the ambidextrous body makes the model practical for both right- and left-handed users.

KensingtonKonnect allows users to assign program functions to the two buttons and adjust cursor and scrolling speeds. That is sufficient for common productivity tasks, although it is less flexible than the SlimBlade Pro with its eight sets of programmable buttons. ChromeOS users can access basic HID functions, but customization through KensingtonWorks is not available for that platform.

This model is best for someone who values a familiar mechanical scroll ring and straightforward trackball operation over wireless flexibility. It is a natural choice for a fixed workstation, particularly for users who want precise optical tracking and a detachable wrist rest without a rechargeable battery.

Tactile Document Navigation

The mechanical scroll ring provides clear physical feedback while moving through long documents, spreadsheets, or web pages. Its rotating action also offers a more deliberate alternative to a small wheel.

A Familiar Orbit Foundation

The 40mm optically tracked ball and detachable wrist rest create a balanced, recognizable Orbit experience. The two-button layout keeps the device approachable while preserving essential customization.

4. Kensington Orbit Trackball – Best Simple Wired Value

4.2Editor scoreCheck price on Amazon

Kensington Orbit Trackball Mouse

40mm optical tracking ball

Wired USB connectivity

Compact ambidextrous shell

Two programmable buttons

The Kensington Orbit Trackball Mouse in Silver/Black is a straightforward wired option for users who want a trackball without wireless setup or battery management. Its 4.2 rating supports its reputation as a practical, compact pointing device, with optical tracking and a compact ambidextrous housing.

Pros

• Simple reliable wired setup
• No battery replacement required
• Compact footprint saves desk space
• Optical tracking supports accuracy
• Ambidextrous for either hand

Cons

• No scroll ring included
• Limited two-button customization

We may earn a commission when you buy through this link, at no additional cost to you.

Internal red optics track the 40mm ball to place the cursor accurately while reducing the arm movement associated with a conventional mouse. Its wired USB connection provides straightforward installation, consistent power, and freedom from charging routines. It also uses less desk space than the movement envelope of a standard mouse.

The main limitation is the absence of a scroll ring. Users will need to use a standard wheel or configured button for scrolling rather than the distinctive rotating control found on other Orbit models. KensingtonKonnect supports assigning functions to each of the two buttons and adjusting cursor speed, but the customization depth is modest.

This is the most sensible pick for a fixed office desk, a shared computer, or a buyer who values simplicity. It is especially attractive for people who dislike wireless pairing and want a trackball that begins working with a dependable USB connection.

Reliable Power Without Batteries

Wired USB power removes charging and battery replacement from the equation. That makes the model dependable for long sessions and attractive for permanent installations where a consistent connection matters.

Space-Saving Pointing

The stationary body leaves more usable desk area than a mouse that must travel across a surface. Its ambidextrous form also makes the device suitable for either hand without changing the layout.

5. Kensington Wired SlimBlade – Best Low-Profile Comfort

4.3Editor scoreCheck price on Amazon

Kensington Wired SlimBlade Trackball Mouse

Low-profile silver housing

Reliable wired USB

Laser tracking technology

Free button customization

The Kensington Wired SlimBlade Trackball Mouse emphasizes a low-profile shape, laser tracking, and reduced arm movement. Its 4.3 rating makes it one of the stronger choices in the guide for users who prefer the slimmer visual and physical design associated with the SlimBlade family.

Pros

• Low-profile shape reduces hand strain
• Laser system supports precision
• Ambidextrous for either hand
• Uses less desk space
• Supports software customization

Cons

• Older wired-only design
• Less connectivity than newer models

We may earn a commission when you buy through this link, at no additional cost to you.

Unlike the larger Expert and SlimBlade Pro models, this wired version uses laser tracking for cursor control. The silver metallic finish gives it a restrained professional appearance, while the low-profile chassis reduces the height of the hand compared with a more elevated trackball design.

KensingtonWorks provides button customization, allowing shortcuts or program functions to be assigned for a more productive workflow. The ambidextrous shape is valuable for users who periodically switch hands or use a shared workstation. As a wired device, it does not need batteries, pairing, or a receiver.

Its chief limitation is that the wired-only format lacks the connection flexibility of the Expert, SlimBlade Pro, and newer wireless Orbit models. Still, it may be the most comfortable option for someone specifically searching for a low-profile trackball with a dependable USB connection.

Low-Profile Hand Positioning

The shallow body keeps the hand at a relatively low angle and occupies less vertical space than a traditional mouse. That can make long work sessions feel more natural and preserve room on a crowded desk.

Simple Wired Precision

Laser tracking and wired USB create a straightforward pointing experience without wireless administration. KensingtonWorks adds a layer of control for users who want shortcuts without additional hardware.

6. Kensington Orbit Wireless Scroll Ring – Best Balanced Wireless Orbit

4.2Editor scoreCheck price on Amazon

Kensington Orbit Wireless Scroll Ring

40mm precision tracking ball

Bluetooth and 2.4GHz wireless

Four selectable DPI levels

Removable ergonomic wrist rest

The Kensington Orbit Wireless Trackball with Scroll Ring combines the familiar 40mm ball and mechanical ring with modern wireless flexibility. Its 4.2 rating indicates a balanced product that serves both everyday browsing and detailed work while retaining the tactile qualities of the Orbit line.

Pros

• Two wireless connection methods
• Tactile mechanical scroll ring
• Four DPI choices for varied work
• Detachable wrist support
• Encrypted 2.4GHz wireless connection

Cons

• Battery life is not specified
• Software support may vary by platform

We may earn a commission when you buy through this link, at no additional cost to you.

Bluetooth 3.0 and Low Energy connectivity provide two wireless options, while the 2.4GHz receiver uses 128-bit AES encryption. Four DPI settings—400, 800, 1,200, and 1,600—let users move between precision editing, word processing, and casual navigation without changing the hardware.

KensingtonKonnect supports button assignment, shortcut configuration, and adjustments to cursor and scrolling speed. The detachable wrist rest provides soft support for extended use, and the ambidextrous design works for either hand. Optical tracking and the precisely shaped 40mm ball support controlled movement with less hand and arm activity.

Unlike the SlimBlade Pro, this model does not list rechargeable battery life, and the product data does not specify a USB-C charging arrangement. That makes it important to verify battery requirements before buying. Otherwise, it is a compelling middle ground for users who want wireless Orbit ergonomics and a mechanical scroll ring.

Four Speeds for Different Tasks

The selectable DPI range makes the same ball usable for slow, precise pointer placement and faster movement across the screen. This is particularly helpful when switching between editing, word processing, and general navigation.

Wireless With Physical Scrolling

The Orbit name is often associated with a tactile scroll ring, and this model preserves that feature while removing the cable. Bluetooth and encrypted 2.4GHz options allow users to choose the most convenient connection for their setup.

7. Kensington Orbit Touch Scroll Ring – Best Compact Wireless Option

4.2Editor scoreCheck price on Amazon

Kensington Orbit Touch Scroll Ring

Compact 32mm trackball

Touch-based scroll ring

Bluetooth and USB receiver

Small-to-average hand fit

The Kensington Orbit Wireless Trackball Mouse with Touch Scroll Ring is built for users who want a compact wireless device rather than a large ergonomic platform. Its 4.2 rating reflects a well-liked combination of a 32mm ball, touch scrolling, plug-and-play operation, and support for both Bluetooth and a USB receiver.

Pros

• Very compact desk footprint
• No drivers required for setup
• Touch scrolling supports navigation
• Wireless receiver and Bluetooth
• Designed for smaller hands

Cons

• Smaller ball than most rivals
• Not intended for large hands

We may earn a commission when you buy through this link, at no additional cost to you.

The 32mm ball is noticeably smaller than the 40mm and 55mm balls used by other models in this guide. That makes the Orbit appropriate for small to average-sized hands and for users who prefer a smaller, less dominant pointer. The touch-scroll ring allows fingers to glide through pages and documents without a protruding wheel.

Setup requires no drivers, while KensingtonKonnect supplies further customization for users who want a tailored productivity experience. Bluetooth LE can be useful for streamlined laptop use, and the USB nano receiver provides an alternative for desktops or systems where a receiver is more convenient.

The compromise is ball size and intended fit. People with larger hands may find the 32mm ball less comfortable or less precise than a medium or large model. Within its target audience, however, it offers a neat, uncluttered solution with essential wireless flexibility.

Compact for Constrained Desks

A 32mm ball and small housing take up considerably less room than the larger Expert and SlimBlade models. This can be useful in compact offices, shared workspaces, or setups where every inch of surface area matters.

Simple Wireless Setup

The device supports Bluetooth LE and a USB nano receiver, giving users a straightforward way to connect different systems. Its no-driver setup helps reduce installation friction, while KensingtonKonnect remains available for deeper personalization.

8. Kensington Orbit Optical Trackball – Best Minimal Wired Design

4.0Editor scoreCheck price on Amazon

Kensington Orbit Optical Trackball

40mm precision tracking ball

Optical cursor control

Wired USB plug-and-play

Compact ambidextrous design

The Kensington Orbit Optical Trackball Mouse offers a pared-back wired design centered on a medium 40mm ball, optical tracking, and plug-and-play USB installation. Its 4.0 rating makes it a dependable option for anyone who primarily needs accurate, space-saving pointer control.

Pros

• Straightforward USB installation
• Compact stationary footprint
• Perfectly spherical tracking ball
• Works for either hand
• No wireless setup required

Cons

• No detailed customization details listed
• Basic feature set

We may earn a commission when you buy through this link, at no additional cost to you.

The ball is designed as a perfect sphere, which helps it roll consistently and provides a familiar trackball feel. Optical tracking is used to interpret movement accurately, while the stationary housing avoids the repeated lateral motion required by a conventional mouse. The ambidextrous design supports both right- and left-handed use.

Its simplicity is the main appeal. A wired USB connection requires little setup, avoids battery concerns, and works well for a permanent computer station. The compact footprint also leaves more room for keyboard movement, writing, or other tools than a full-size mouse.

The product data does not highlight a scroll ring, removable wrist rest, or extensive software-based control, so buyers should not expect the feature set of the newer Orbit models. It is best suited to users who prioritize an uncomplicated 40mm optical trackball and a compact, dependable wired design.

Consistent Sphere Tracking

The precisely shaped 40mm ball is designed to roll evenly under the fingers. Its medium size offers a middle ground between the compact 32mm model and the larger Expert and SlimBlade Pro designs.

No-Fuss USB Operation

Plug-and-play wired USB removes the need for drivers, batteries, or receiver pairing. This makes the trackball a natural fit for office computers, kiosks, and other stable setups.

9. Kensington TB675 Vertical Trackball – Best Multi-Device Productivity

3.8Editor scoreCheck price on Amazon

Kensington TB675 Vertical Trackball

60-degree vertical housing

34mm thumb-operated ball

Four-device connectivity

Nine programmable buttons

The Kensington TB675 Wireless Vertical Trackball is the most unconventional choice here, using a 60-degree vertical tilt, a 34mm thumb-operated ball, and a device selector for as many as four connected systems. Its 3.8 rating is the lowest in the group, but its specifications strongly appeal to multi-device users.

Pros

• Supports up to four devices
• Rechargeable USB-C design
• Natural wrist and thumb positioning
• Metal multidirectional scroll wheel
• Extensive button and macro control

Cons

• Lower rating than other models
• Vertical form may need adjustment

We may earn a commission when you buy through this link, at no additional cost to you.

The contoured vertical shape is intended to support more natural wrist and thumb positioning, particularly for average-sized hands. Rather than rolling a ball with the index finger, users operate the smaller trackball with the thumb. This arrangement works with the device's metal 4D scroll wheel, nine buttons, and configurable side controls.

Triple connectivity includes a 2.4GHz dongle with 128-bit AES encryption, dual Bluetooth, and a wired USB-C connection. A built-in selector makes it possible to move among four devices, while a rechargeable design removes disposable battery waste. KensingtonKonnect can assign shortcuts and macros across the button set.

Its lower rating suggests that some users may not find the vertical shape comfortable or may need time to adapt to thumb movement. The listed fit is also oriented toward average-sized hands. For a user managing several computers who values productivity controls over a conventional horizontal layout, however, it is a highly specialized and capable choice.

Thumb-Operated Vertical Control

The 60-degree angle and thumb-driven ball create a different movement pattern from standard Orbit and SlimBlade models. The change can encourage a more neutral wrist position, although users may need time to build muscle familiarity.

Four Computers, One Device

The built-in device selector and support for dual Bluetooth, 2.4GHz, and wired USB-C make the TB675 well suited to mixed workspaces. A user can move between a laptop, desktop, and additional paired systems without relying on separate pointing devices.

10. Kensington Slimblade Trackball – Best Refined Low-Profile Choice

4.5Editor scoreCheck price on Amazon

Kensington Slimblade Trackball

Slim low-profile housing

Compact stationary footprint

Trackball-based pointer control

Classic Kensington styling

The Kensington Slimblade Trackball has a 4.5 rating, the highest numerical score among the ten products. Its slim form factor and understated appearance make it appealing to users who want a trackball that does not dominate the desk while still providing the familiar benefit of stationary pointer control.

Pros

• Highest rating in the guide
• Slim shape suits focused desks
• Stationary operation saves space
• Refined minimalist appearance
• Familiar trackball interaction

Cons

• Limited published specification detail
• Confirm current connectivity and features

We may earn a commission when you buy through this link, at no additional cost to you.

The product listing identifies the Slimblade as model K72327US, connecting it with Kensington's established low-profile trackball design. Its visual simplicity is especially relevant for professional environments where a large, highly contoured device might feel out of place. Because the device remains stationary, it also requires less operating space than a mouse.

The available product data is limited compared with the other listings, so details such as the exact sensor system, included software, current connection method, and accessory contents should be confirmed on the retailer page. It is also important to distinguish this listing from the newer SlimBlade Pro, which offers a rechargeable battery and substantially more extensive specifications.

With the highest rating in the collection, the Slimblade is a strong option for a buyer who prioritizes a slim appearance, minimal desk presence, and a proven trackball format. It is best suited to those who can confirm that the current version's controls and connectivity meet their needs.

Subtle Desk Footprint

The low-profile housing is designed to sit neatly beside a keyboard without the visual bulk of a larger ergonomic mouse. Its stationary operation also keeps the pointer device in one place throughout the day.

A Highly Rated SlimBlade

Its 4.5 rating is the strongest customer-rating figure in this guide, making it notable even though the product data lists fewer technical details. Buyers should review the final listing carefully to confirm the features relevant to their setup.

Buying Guide – How to Choose the Best Kensington Trackball

The right Kensington trackball depends less on raw feature count than on fit, control method, and connection requirements. Comparing ball size, scrolling hardware, programmability, power, and platform support will help you avoid paying for capabilities you do not need.

Ball Size and Finger Fit

Kensington offers 32mm, 34mm, 40mm, and 55mm balls across this guide, and the difference can materially affect control and comfort. A smaller ball may suit smaller hands and compact desks, while a larger surface gives the fingers more room to guide the pointer with finer movements. The 40mm Orbit models provide a middle-ground option for users who want precision without a very large mechanism.

Match the ball to your hand rather than selecting solely by measurement. Consider which finger will roll it, whether the device is thumb-operated or finger-operated, and whether your fingertips tend to rest on the shell while moving. A ball that feels cramped can encourage more tension over a long workday.

Traditional or Vertical Shape

Most Kensington trackballs use a low or moderately raised horizontal housing, while the TB675 uses a pronounced 60-degree vertical angle and a thumb-operated ball. Traditional models are familiar to many users and may be easier to transition into. A vertical design may promote a more neutral wrist angle, but it changes the hand-to-device relationship substantially.

Choose the shape you can maintain comfortably. A vertical model is not automatically more comfortable for every person, and the TB675 is specifically described as best suited to average-sized hands. Users who are uncertain may prefer a slim horizontal model such as the Expert or SlimBlade family.

Connection Method

Wired USB provides the simplest and most consistent approach, but it keeps the device attached to one computer. Wireless 2.4GHz receivers are convenient for switching between systems and can include encryption, while Bluetooth reduces receiver clutter on compatible laptops and desktops. The SlimBlade Pro goes further by supporting Bluetooth, 2.4GHz, and a wired USB-C connection.

Count your computers and decide whether you value mobility or setup simplicity. Check Bluetooth version support, whether a USB receiver is included, and whether a USB-C adapter is necessary. Also verify that your operating system falls within the published compatibility range.

Scroll Ring and Wheel Choice

Kensington's Orbit models are closely associated with scroll rings, which provide physical rotation for vertical navigation. Some rings are mechanical, while the compact Orbit Wireless with Touch Scroll Ring uses a touch gesture along the ring. The TB675 instead uses a metal 4D wheel that supports vertical and side-to-side movement, and other models rely on conventional scrolling controls.

Think about the length and type of your scrolling tasks. A ring can be precise in long documents, while a standard wheel may be familiar and compact. A multidirectional wheel is useful for wide timelines, spreadsheets, and side-to-side navigation. Check the product's exact controls because scrolling behavior is not identical across the range.

Programmable Buttons and Software

The number of customizable buttons varies considerably. The basic Orbit models provide two programmable buttons, the Expert offers a four-button customizable design, the SlimBlade Pro supports eight sets of programmable buttons, and the TB675 provides nine programmable buttons. KensingtonKonnect and KensingtonWorks are used for assigning shortcuts, changing cursor or scrolling speeds, and creating profiles.

Prioritize programmability if you work in demanding applications or repeat the same commands throughout the day. If you only need basic clicking and scrolling, two buttons may be enough. Review platform limitations too: ChromeOS users can use HID functions on some models but may not be able to customize them, and Windows ARM support is not currently available for several products.

Wrist Rest and Desk Space

A detachable wrist rest can improve the experience during extended use, particularly on models that place the hand at a raised angle. The Expert, wired Orbit with Scroll Ring, and wireless Orbit Scroll Ring include this feature. Slim designs take up little room without a separate rest, while the TB675 and larger Expert naturally require more surface area.

Choose based on your available space and the amount of support you want. A rest is useful if you tend to brace the heel of your hand against the device or desk. If you prefer a low-profile setup, a model without a rest may feel cleaner and leave more room to move.

Power, Rechargeability, and Travel

A wired model needs no battery and works consistently at a permanent desk. Wireless Orbit models provide cordless freedom but require you to verify the battery format and expected runtime because the product data does not state those details for every model. The SlimBlade Pro and TB675 use rechargeable USB-C power, with the SlimBlade Pro stated to offer up to four months on one charge.

Rechargeable models suit people who dislike disposable batteries and want to travel with one pointing device. Wireless Orbit models can be equally convenient for desk-to-laptop movement. Always check battery status, charging cable, receiver storage, and included adapters before ordering.

How to Use and Care for Your Kensington Trackball

Begin by placing the trackball where you can reach the ball without raising your shoulder or extending your wrist. For a finger-operated model, rest the index or middle finger lightly on top and move the ball with small, controlled movements. For the TB675, position the thumb on its smaller ball and avoid squeezing the surrounding housing. Adjust the cursor or DPI speed before beginning detailed work so the pointer does not require constant correction.

Connect the device using the method that matches your computer. Wired versions can usually be used after connecting USB, while Bluetooth models require pairing and 2.4GHz models require their included receiver. Install KensingtonKonnect or KensingtonWorks if you want to customize buttons, cursor speed, or scrolling behavior, and confirm that your operating system is supported. Rechargeable models should be charged with their specified USB-C cable, while wireless Orbit models should use the battery arrangement specified in their product documentation.

Keep the ball clean and free of dust, crumbs, oil, and sticky residue because debris can affect rolling and sensor performance. Remove the ball only as directed by the included guide, clean it with a soft dry or lightly damp cloth, and avoid abrasive cleaners or liquid poured into the device. Wipe the exterior and wrist rest regularly, keep openings unobstructed, and store a wireless model with adequate battery charge. If movement becomes uneven or the cursor drifts, power the device off, clean the ball and sensor area, and test it again on another surface.

Frequently Asked Questions

Is a Kensington trackball better than a standard mouse?

A trackball can be more comfortable for many people because it keeps the device stationary and reduces repeated arm movement. It also tends to require less desk space and offers distinctive scrolling or programmable controls. Comfort still depends on ball size, hand shape, grip technique, and adjustment period, so a mouse may remain preferable for some gaming, precision, or highly personalized workflows.

Which Kensington trackball is most suitable for small hands?

The Orbit Wireless Trackball Mouse with Touch Scroll Ring is explicitly designed for small to average-sized hands and uses a compact 32mm ball. The TB675 is described as suitable for average-sized hands, while the 40mm Orbit models offer a middle-ground option. A smaller device does not automatically guarantee comfort, so hand position and the way you roll the ball still matter.

Do Kensington trackballs work with Mac and Linux computers?

The Expert supports macOS 10.14 and later and Chrome OS 44 and later, while the basic Orbit lists macOS 10.8 and later and Chrome OS 44 and later. The wireless Orbit Scroll Ring is identified as Mac and PC compatible. Linux and additional platform support are not confirmed in the supplied data, so check the current manufacturer and retailer requirements before purchasing.

What is the difference between a scroll ring and a scroll wheel?

A scroll ring rotates like a small dial and often provides distinct tactile feedback during vertical scrolling. A standard wheel rolls under a finger, while the TB675's 4D wheel also tilts for side-to-side movement. The Orbit Wireless with Touch Scroll Ring uses a touch gesture along the ring rather than a conventional wheel.

Can I customize the buttons on a Kensington trackball?

Most models in the guide support button assignment and speed adjustments through KensingtonKonnect or KensingtonWorks. The number of programmable buttons varies from two on basic Orbit models to nine on the TB675, and the SlimBlade Pro supports eight sets of programmable buttons. Some ChromeOS configurations support standard HID functions without full customization, while Windows ARM support is currently absent on several listed products.

Which Kensington trackball is easiest to use with multiple computers?

The SlimBlade Pro supports Bluetooth, 2.4GHz wireless, and wired USB-C, making it the most flexible listed model. The TB675 can connect up to four devices and includes a built-in selector, while the Expert and wireless Orbit models offer two connection modes. The best choice depends on the number of computers, operating systems, and whether you value wireless freedom or wired reliability.

Are wireless Kensington trackballs rechargeable?

The SlimBlade Pro and TB675 explicitly use rechargeable USB-C batteries. The wireless Orbit products do not have a rechargeable specification in the supplied information, so their battery type and replacement process should be confirmed before ordering. Wired models need no battery and avoid both charging and battery-replacement concerns.

How do I clean a Kensington trackball?

Power it off, remove the ball according to the product guide, and wipe away dust or residue with a soft, lightly dampened cloth. Keep moisture away from openings and never pour liquid into the sensor area. Clean the wrist rest and exterior as well, reinstall the ball only when it is dry, and test the cursor for smooth movement afterward.

Final Thoughts on Choosing the Best Kensington Trackball

The Kensington Expert Wireless Trackball is the most balanced overall recommendation because it combines a 55mm ball, precise optical tracking, a detachable wrist rest, two wireless connection methods, and useful customization. The SlimBlade Pro is the stronger premium option for extensive programmability, rechargeable power, and the ability to work over Bluetooth, 2.4GHz, or USB-C.

For simpler setups, the wired Orbit Trackball Mouse provides a dependable, battery-free experience without unnecessary complexity. The wired Orbit with Scroll Ring adds tactile scrolling, the wireless Orbit Scroll Ring adds encrypted receiver support and selectable DPI settings, and the compact touch-scroll Orbit favors smaller desks and hands. Prioritize fit before features, because a comfortable ball and housing matter more than an extra button or connection mode.

Review the current product listing before ordering to confirm compatibility, included receivers or cables, battery requirements, warranty coverage, and the latest accessories. Kensington trackball prices and promotions can change, and seller availability may vary, so comparing the final listing can help ensure that the selected model fits both your workflow and budget.
