Ergonomic trackball for medium and large hands

The Kensington Pro Fit Ergo TB450 is a right-handed trackball designed for medium and large hand sizes. It uses an optical sensor fixed at 1600 dpi for precise cursor control. The white finish gives it a clean, professional appearance on any desk.

Sustained comfort through stationary operation

Because the ball stays in place, the hand and wrist remain stationary during long sessions. This reduces the repetitive arm motion that conventional mice require. The AA battery powers the device without a cable, so there is no drag or charging downtime to interrupt workflow.

Dual wireless connectivity with simple mounting

The trackball connects via Bluetooth or the included 2.40 GHz USB receiver, letting users choose the link that suits their setup. A single AA battery slots into the base for quick replacement. The medium and large palm contour supports a relaxed grip day after day.

Questions about this item

Does the Kensington Pro Fit Ergo TB450 trackball generate noticeable heat or noise during all-day use?

The optical sensor and wireless electronics draw very little power from the single AA battery, so the trackball stays cool and silent even after hours of continuous operation.

What must I already own to start using the K72179WW trackball right away?

You need one AA battery and an available USB port for the 2.40 GHz receiver; Bluetooth pairing works without extra hardware if your computer supports it.

Will the 1600 dpi optical sensor work reliably on the same desk surface I use with my older mouse?

Yes, the 1600 dpi optical sensor tracks on most standard desk surfaces that older optical mice handle, so you can keep your existing mouse pad or desk finish.
