Kensington Orbit™ Wireless Trackball with Scroll Ring - Black

• Dual wireless capability allows for both 2.4 GHz and Bluetooth (3.0 and LE), with 128-bit encryption

• The scroll ring allows you to easily rotate the wheel and scroll up and down web pages or documents. The 40mm ball has a hard surface and is specially shaped as a perfect spherical ball for precise tracking and control.

• Four DPI settings make it easy to adjust the cursor speed to your needs by selecting the appropriate level (400, 800, 1,200, or 1,600) - lower DPI settings are ideal for precise editing, and higher DPI settings are ideal for word processing or browsing.

• Symmetrical design is suitable for both right- and left-handed users. The ball mouse reduces wrist and hand movements, helping to reduce the risk of repetitive stress injuries.

• Free downloadable KensingtonWorks™ software provides a personalized experience by assigning various functions (including hotkeys) to buttons and adjusting cursor and scroll speeds.

• Optical tracking technology ensures precise cursor movement and excellent accuracy, so you can quickly reach the right place on the screen with fewer hand movements, increasing productivity and efficiency.

• Removable wrist rest provides a soft cushion that supports your hand and wrist for ergonomic comfort to prevent pain and maintain productivity during extended computer use.

• Compatible with Mac and PC.
