Kensington Expert Mouse Pro Trackball
Precision Control — Without Moving the Mouse
The Kensington Expert Mouse Pro is an ambidextrous trackball designed to provide precise cursor control while remaining stationary on the desk.

The best trackball ever made has just gotten better.
The Expert Mouse Wired Trackball is the ultimate productivity enhancer that makes working at the desk quicker, more accurate and extremely comfortable for your hand and wrist.

Who Is It For?
Suitable for users who:
- undertake frequent or precision cursor work
- want a stationary alternative to a conventional mouse
- have limited desk space for mouse movement
- want to use either the left or right hand
- prefer fingertip control rather than moving the entire mouse
- want programmable controls for frequently used functions
Problem to Solve
A conventional mouse requires repeated movement across the desk surface, often using the same hand and arm throughout the working day.
The Expert Mouse Pro remains stationary, while cursor movement is controlled through the central trackball.
Its ambidextrous layout also allows the device to be positioned for either hand, helping users vary their working arrangement.
