The Kensington trackball legacy continues with the latest addition to the patented Orbit Trackball with Scroll Ring — the Orbit Wireless Trackball with Scroll Ring. You asked for wireless, and we delivered, with the same great features that have made the Orbit Trackball with Scroll Ring so popular, including a patented scroll ring that allows you to scroll up and down pages with ease; customizable buttons; dual wireless connectivity offering the flexibility of 2.4 GHz and Bluetooth (3.0 and LE), with 128-bit AES government-grade encryption security; four DPI settings (400, 800, 1,200, or 1,600) that let you easily adjust the cursor speed to fit your needs; a detachable wrist rest; ambidextrous design; and plug-and-play ease for Mac or PC.

Mac and PC compatible. 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. 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. Free KensingtonWorks downloadable software provides a personalized experience, giving you the ability to assign a variety of functions (including shortcuts) to the buttons, and adjust cursor and scrolling speed. Ambidextrous design works equally well for right-handed and left-handed users. Trackball reduces wrist and hand movement to ease repetitive-stress injuries. 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. 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. Dual wireless connectivity offers the flexibility of 2.4 GHz and Bluetooth (3.0 and LE), with 128-bit AES government-grade encryption security.
