The Kensington trackball legacy continues with the Orbit® Wireless Trackball with Scroll Ring. This trackball features a patented scroll ring that allows you to scroll up and down pages with ease, customisable buttons, dual wireless connectivity (2.4 GHz, Bluetooth 3.0 and LE) with 128-bit AES government-grade encryption security, four DPI settings (400, 800, 1,200, or 1,600) to easily adjust the cursor speed to fit your needs, a detachable wrist rest, ambidextrous design and plug-and-play ease for Mac or PC. The scroll ring lets you spin the dial to move up and down web pages or documents with complete ease. And the 40mm ball’s hard surface is specially designed as a perfect sphere for precise tracking and control. 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. Optical tracking technology delivers precise cursor movement for superior accuracy, so you can get where you want on the screen quickly with less hand movement, improving productivity and efficiency. A detachable wrist rest delivers soft cushioning to support the hand and wrist in ergonomic comfort for pain-free productivity during extended periods of activity on the computer. Mac and PC compatible.
