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.
