My wireless mouse dies about once a month. And God forbid I use the built in touch pad! This Battery Free Wireless Mouse needs no batteries at all. The mouse is powered by an electrical field emitted from the mouse pad, powered from the USB port.
The high quality optical mouse never needs to have batteries replaced since their simply isn’t any. It keeps going, and going, and going. Without the help of batteries. Take that Energizer Bunny, you cocky bastard. — Andrew Dobrow
