SteelSeries XAI
The SteelSeries XAI earns a record in our book for having the most useless feature in the roundup. Drum roll please... an LCD display on the underside of the mouse. Yep. A display, that in the normal operation of the product, will never be seen. From what we can make out, this little LCD displays the firmware version of the mouse, and the firmware version update process (which is also shown in the software on your PC, by the way...).

That folly aside, the XAI is a pretty nice mouse. It’s got a very comfortable and mirrored design, with “enough” buttons, but not overloaded as some mice tend to be. This mouse is suitable for left handers, as it’s a mirrored design. Unfortunately, that’s also part of its downfall. The thumb buttons are mirrored on both sides of the mouse, and because of that, there’s two buttons under where you’d grip the mouse normally with the fourth and fifth fingers. We found we were often scraping those fingertips on the mousing surface. Needless to say, bigger or smaller fingers may find it a different experience. DPI switching is the same as the KINZU mouse, and overall, the XAI is comfortable and responsive.
Available from SteelSeries, retailing for $129.95.
