I know they have the laser mouses now too, but this is about the best $40 I've ever spent. The optical technology is awesome. No more sticking mouse and problems with photoshop or internet games. It also has 4-way scrolling capability (no need to use the scroll bars). Also, there is a button for instant magnification up to 5X.
All in all, an awesome devise for only $40.
