Input:
As a lefty, mouses for us are few and far between. The mouse is great for people with larger hands such as myself, and the accuracy and convenience of optical mice is far superior to the infernal wheel/trackball setup. My right handed brethren have no problem using it as well; the mouse is for both. I never have to clean it, and the cursor never ever jumps or skips. It also has a cool red glow when you turn your computer on. The reason it doesn't get five is becuase the mouse reqires that you install Microsoft's intellimouse software. The program runs in your system tray and eats up a few megs of RAM while it sits there and does nothing. You can disable it, but good luck trying to get the 4th and 5th buttons to work. I still would but this mouse again however, it does its job excellently. Shame on Microsoft for requiring installation of worthless software however.
