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*. Keep using your mouse for up to eight months with a single battery, and rely on the power indicator to tell you when it’s time to replace it.
Snap-in Nano Transceiver:
When it’s time to pack up and go, you’ll hardly notice the tiny transceiver. Keep it plugged into your computer’s USB port, or tuck it into the underside of the mouse for travel. When stowed, the transceiver turns off the mouse to conserve battery life. The Nano Transceiver is so small that it sticks out less than a centimeter from the USB port and can easily remain plugged into the computer when traveling.
