The Kensington Expert Wireless Trackball Mouse fundamentally changes how you interact with your computer by eliminating wrist movement entirely. In our testing, we found that keeping the hand stationary while rolling the large trackball significantly reduces the strain typically caused by traditional mice. Rather than forcing your wrist into unnatural angles, this trackball relies on finger movement for cursor control.
Kensington Expert Wireless Trackball Mouse
Overview
The trackball centers around a 55mm ball paired with Diamond Eye optical tracking. After using the device, we noted the oversized ball delivers highly precise cursor control without requiring any arm movement. The patented scroll ring surrounding the ball allows for rapid scanning of long web pages and documents. Because the layout is completely symmetrical, left-handed and right-handed users experience the exact same performance.
A detachable ergonomic wrist rest supports your hand during long work sessions, though it removes easily for a lower desk profile. The trackball features a four-button layout customized via KensingtonWorks or KensingtonKonnect software. This software controls button assignments, scroll speed, and cursor sensitivity, letting you match the hardware to your specific workflow.
Connectivity options include built-in Bluetooth LE and a 2.4Ghz USB dongle. To extend battery life, an auto-sleep function activates during periods of inactivity. You can adjust these power-saving settings directly within the KensingtonWorks software to minimize battery replacements.
Who It’s For
This trackball suits computer users who experience wrist pain from traditional mice. It serves as a practical choice for people with limited desk space since the device stays in one spot. Left-handed users benefit from the completely symmetrical layout. Anyone who spends long hours reading through documents will appreciate the dedicated scroll ring.
Tracking and Scanning Mechanisms
A larger ball, such as a 55mm diameter, combined with optical tracking provides precise cursor control. Dedicated scanning hardware, like a physical scroll ring, allows for faster document reading compared to standard scroll wheels.
Ergonomics and Customization
Look for devices offering a detachable wrist rest to support your hand during long sessions. Ambidextrous layouts accommodate both right- and left-handed users. Software customization is critical for assigning specific functions to the buttons and adjusting cursor sensitivity.
Connectivity and Power
Dual wireless options, including Bluetooth LE and a 2.4Ghz USB dongle, ensure compatibility across different computers. Built-in auto-sleep functions help conserve battery power during inactivity.
