• Dual wireless connectivity offers the flexibility of 2.4 GHz and Bluetooth LE, with 128-bit AES government-grade encryption security
• 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
• Ambidextrous design works equally well for right-handed and left-handed users. Trackball reduces wrist and hand movement to ease repetitive-stress injuries
• Free *KensingtonKonnect 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. *Windows ARM-based computers are currently not supported.
