Microsoft Wireless Mobile Mouse 3500 - Black Gloss
You'll appreciate how this wireless mobile mouse comfortably fits your hand and your mobile lifestyle. Use it just about anywhere, even on a rough park bench or your living room carpet, relying on Microsoft BlueTrack Technology. When its time to pack up and go, youll hardly notice the tiny transceiver. Keep it plugged into the USB port, or stow it in the bottom of the mouse for travel. Keep using your mouse for up to eight months with a single battery, and rely on the power indicator to tell you when its time to replace it.
BlueTrack Technology does not work on clear glass or mirrored surfaces.
