Pro Fit Ergo TB550 Trackball

The Kensington Pro Fit Ergo TB550 is a wireless trackball mouse designed for users who prefer stationary cursor control. It connects via Bluetooth or a 2.40 GHz radio frequency link, offering flexibility across devices. The optical sensor operates at 1600 dpi for precise tracking without moving the whole unit.

Rechargeable Battery and Seven Buttons

The built‑in rechargeable battery removes the need for disposable cells, charging through a USB Type‑C port. Seven programmable buttons let you assign shortcuts or macros to suit specific workflows. A tilt wheel adds horizontal scrolling alongside the standard vertical wheel.

White Finish and Wireless Freedom

The white chassis gives a clean, modern look that fits office or home setups. Wireless operation eliminates cable clutter on the desk, while the trackball form factor reduces arm movement during long sessions. Buyers who need a traditional sliding mouse or more than seven programmable inputs should consider other form factors.
