Kensington Expert Trackball

The Expert Mouse Wireless Trackball supports dual connectivity via Bluetooth 5.0 LE or a 2.4 GHz USB receiver. While you can switch between connection methods, it does not support simultaneous multi-device pairing.

Yes, it is designed with an ambidextrous shape that accommodates both left- and right-handed users. It also includes a detachable wrist rest to help support your hand and wrist during long work sessions.

The trackball will function as a standard mouse immediately upon connection. However, to customize the button functions or adjust the cursor speed, you will need to download the KensingtonWorks software.

The patented Scroll Ring is a physical dial surrounding the trackball itself. By rotating the ring with your fingers, you can scroll up and down through documents and web pages more fluidly than with a standard scroll wheel.

The Expert Mouse Wireless Trackball is compatible with Windows 7 and later, macOS X 10.8 and later, and Chrome OS 44 and later.

The device runs on AA batteries and features an automatic power-saving sleep function that engages when the trackball is not in use. This helps extend battery life significantly without requiring you to manually turn it off.
