Tweaknews.net posted a review on the Saitek GM3200 3200dpi Laser Gaming Mouse

Despite its large size, I found this mouse to be a pleasure to use. With six programmable buttons, four DPI settings that can be changed on-the-fly, and removable weights it will appeal to a wide range of gamers with all the customization options. Response time is superb and two button profiles can be saved with Saitek's SST programming software. Even the traction on the bottom of the mouse can be adjusted by flipping over the weight covers.
