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 & 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 More from the Manufacturer

The Kensington Orbit Trackball with Scroll Ring is a wired stationary pointing device for desk users who want to move the cursor from one spot instead of sweeping a mouse across a pad. A 40 mm space gray ball sits at the center of the housing and is driven with the fingertips, so the wrist and forearm stay still and no clear tracking surface is needed beside the keyboard. Wrapped around the ball is the scroll ring, a rotating collar that scrolls long documents, spreadsheets, and web pages in either direction with one finger and offers smoother, more gradual control than a stepped wheel. Two buttons flank the ball, and both can be reassigned through the free KensingtonWorks utility so frequent commands sit under the fingers already resting on the device. The shell is symmetrical, giving left and right hand users identical reach to the ball and the same button geometry, and a detachable wrist rest clips to the front edge to lift and cushion the heel of the hand for longer sessions. Optical tracking handles cursor movement without a mechanical roller, and the ball lifts free for periodic cleaning. Connection is plug and play over USB-A with no driver download, and the assembly measures 8.7 by 6 by 1.8 inches or 221 by 152.4 by 45.7 mm with the wrist rest attached. Because the housing stays in one place, the trackball suits narrow desks, height-adjustable desks, and shared benches where there is no clear room to sweep a mouse. Windows, macOS, and Chrome OS are supported, and the trackball is backed by a 5-year limited warranty.
