The SideWinder Mouse has some cool features like an LCD display built-in and an included accessory box that doubles as a cable holder. Sensitivity is 200 to 2000 dpi and adjustable on-the-fly. The thumb buttons are strange looking metal buds stacked vertically on the right side of the mouse. At first glance, it seems like one of those poor design calls where you will be ever pressing the spot where your thumb buttons used to be. However, the buttons are very intuitive, the bottom one goes backwards, and the top goes forward. It takes all of a second to get used to the unorthodox layout.
