Built for comfortable right-handed use, the mouse features a scooped right thumb so that you can get an ergonomic grip. Four-way scrolling means you can scroll left, right, front and back. BlueTrack technology works on virtually any surface. Additionally, Bluetooth technology allows you to make a wireless connection to your computer.
