Alcatroz USB Mouse, Shark B.M.Blue

It's an OK mouse. The wheel is rubber, which is nice compared to the plastic wheels you see on cheap mice. Moves very smoothly even on very grained wood and has no lag. So for an $8 mouse why does it not get 5 stars? Only because the top plastic and the bottom meet at an edge, and depending on how you hold your mouse, this edge may be uncomfortable. I will not return it, but I would not buy it again... BUT that is because I have decided that I will no longer buy mice under $10, so far my experience has not been ideal. As a sub $10 mouse it is pretty good.
