Kensington ProFit Ergo TB550 Trackball

Using a mouse may seem familiar, but it can also result in less than precise navigation, tight space on your desk, and tightness in your hand. The Trackball Pro Fit Ergo TB550 brings the convenience of trackball technology to users who want it to improve wrist and forearm alignment or improve areas of limited desk space. The perfect solution for people who want to try a trackball for the first time. Made from 51% recycled plastic, it includes a long-lasting battery, an improved 4D scroll wheel, selectable Low Energy (LE) Bluetooth and 2.4 GHz wireless connections for maximum flexibility, and a patented easy-clean ball system.
