Pros: Compact design.

Cons: I wanted something smaller than the lxxxtech wireless optical that I like a lot. Received it in good order from NewEgg, but found the construction to be "cheap" right from the start. The buttons are flimsy and hard to press. Hard to open the mouse to get to the batteries. The optics do not read well at all - at least, on anything but an ideal "mouse pad". Pay the extra $5 for something better. Don't buy this one.
