Kensington Orbit Optical Trackball

Optical tracking technology delivers precise cursor control at the touch of a finger while the ambidextrous, two-button design provides a familiar user experience for mouse converts. Highly accurate and as easy to use as a regular mouse, but it stays in one place saving valuable desk space.

• Ambidextrous Design
  Works equally well for both right-handed and left-handed users to get the most out of their trackball
• Compact Footprint
  Uses far less desk space to use than a mouse so you can optimize the layout of your workstation
• Plug & Play Installation
  Quickly get clicking and scrolling with fast, simple installation through the reliable wired USB connection, plus it doesn’t need batteries
