The wireless Expert Mouse Trackball from Kensington allows for a wireless connection via Bluetooth 4.0 LE or through a USB nano receiver to any computer or laptop. With the TrackballWorks software, you can easily customize the four buttons and mouse pointer speed. The optical tracking with DiamondsEye technology ensures highly precise cursor control and accuracy. You can enjoy fast and convenient scrolling with the scroll ring. The large ball, with a diameter of 55 mm, enables precise control of every movement. A detachable wrist rest provides a comfortable, ergonomic hand position.

The thoughtful design of the trackball mouse is suitable for both right- and left-handed users. When not in use, the mouse automatically enters sleep mode to extend the life of the AA battery. It is compatible with Windows 7 and above, as well as Mac OS X 10.8 and above when using the USB receiver. A 4.0 LE Bluetooth connection is possible with Windows 8.1, 10, and Mac OS X from 10.8. On a Mac, TrackballWorks only works with a 2.4 GHz connection. The Muse-lusve-SB adapter is included.

Enjoy plenty of freedom of movement without the hassle of tangled cables: USB wireless input devices connect wirelessly to the receiver, which you plug into a free USB port. This input device establishes a direct wireless connection to your Bluetooth-enabled computer. Unlike other wireless devices, it does not require a USB receiver, allowing you to keep your USB ports free for other peripherals.
