This Lexip 3D Mouse is incredibly unique because it includes not only the standard 5 button configuration, L/R/Middle(w/wheel)/forward/ba ck, as well as a standard DPI switcher, but not just one, but two joysticks. The first one is obvious when you look at it; it’s an analog stick jutting out of the side near where your thumb would rest. It also doubles as a button. The other one is most unique; it’s the entire base of the mouse itself. In order to activate it, you tilt the mouse in any of the four cardinal directions, and the axis just moves accordingly. And, of course, you can slide it around your mouse pad or table as you always have with any other mouse.
