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.

Questions about this item

Will the Expert Mouse Wireless Trackball K72359WW work with my Windows 7 desktop using the USB nano receiver?

Yes, the trackball supports Windows 7 through the included 2.4 GHz USB nano receiver, and no Bluetooth pairing is required for that connection.

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.

Does the package include the USB nano receiver and batteries, or must I purchase them separately?

The box contains the trackball, wrist rest, USB nano receiver, two batteries, a quick installation guide and a warranty insert — nothing else is required to start.
