The Wireless Mobile Mouse 3500 works on virtually any surface thanks to Microsoft BlueTrack Technology, which combines the power of optical with the precision of laser. Keep its nano transceiver plugged in when you're on the go, or stow it in the mouse when you're done working.
Battery life of eight months lets you work virtually uninterrupted (battery status indicator tells you when battery power is low)
On/Off switch helps you conserve more battery power by turning your mouse off when not in use
Ambidextrous design makes it comfortable to use with either hand
