## Description

Using a mouse may feel familiar, but it can also provide less-than-precise navigation, cramped desk space—and cramped hands. The Pro Fit® Ergo TB550 Trackball brings the comfort and convenience of trackball technology to users who want to improve wrist and forearm alignment or work in tight areas with limited desktop space. An ideal solution for people who want to try a trackball for the first time, it is made of 51% recycled plastic and includes long-life rechargeable battery, enhanced 4D scroll wheel, choice of Bluetooth® Low Energy (LE) and 2.4GHz wireless connection options for maximum flexibility, and patented ball ejection system for easy cleaning.

## Features

- Wireless trackball mouse provides dual wireless connectivity with the flexibility of Bluetooth LE, or 2.4 GHz wireless with 128-bit AES government-grade encryption security
- 4D scroll wheel supports both vertical and horizontal scrolling; Four DPI settings let you easily adjust the cursor speed to fit your needs by selecting the appropriate level (400, 800, 1,200, or 1,600) — lower DPI for precision editing, and higher DPI for word processing or casual browsing
- Rechargeable battery provides up to 4 months of battery life with a single charge via the USB-C port
- 34mm ball’s hard surface is specially designed as a perfect sphere for precise tracking and control by the optical sensor; patented ball ejection system features a unique, easy-to-clean design with built-in trackball ejection button to effortlessly remove the trackball for cleaning when needed
