Wireless trackball for any hand

The Kensington K72359WW Expert Wireless Trackball connects through Bluetooth 4.0 LE or its included 2.4 GHz USB nano receiver, giving cable-free freedom on Windows, macOS and Chrome OS. Its ambidextrous shape and integrated wrist rest suit left- and right-handed users who prefer stationary cursor control over moving a mouse across the desk.

Four buttons and a scroll ring

DiamondEye optical tracking drives the large red ball for precise cursor movement with minimal hand travel. Four programmable buttons and the surrounding scroll ring handle navigation and shortcuts through KensingtonWorks software, though Chrome OS users receive only basic HID functions without full customisation.

Bluetooth 4.0 and 2.4 GHz limits

Bluetooth 4.0 LE preserves USB ports but caps bandwidth and range compared to newer Bluetooth versions, while the 2.4 GHz dongle occupies one port and can face interference in crowded wireless environments. Both wireless modes add latency versus a wired trackball, so competitive gamers or users needing sub-millisecond response should consider a wired alternative.

How can I confirm the DiamondEye optical tracking is functioning correctly after I connect the trackball?

Move the red ball and watch the cursor respond smoothly; then open KensingtonWorks to verify the sensor is detected and adjust cursor speed if needed.
