Logitech MouseMan Dual Optical Mouse is the best mouse ever made. Two lasers insure ultra-precision, it's not wireless so you never have to worry about changing batteries (I hate that) and it's built to last! This is the only mouse I use...I have two of them and they're both going on ten years now without any problem! Logitech...start making them again!

Logitech decided to go even further with product improvements by integrating a second optical sensor in this mouse. Both sensors work together; if the first one finds itself missing data the second one takes over and vice versa. Logitech claims that this makes the mouse less sensitive to different surfaces and that it improves accuracy because it's never in a situation where data is lacking. In fact, the Dual mouse can be used on any kind of surface - even a translucent grey plastic folder with a slightly raised grid pattern on the surface
