Thought I'd just comment that this mouse has been really useful since I have picked it up. The USB receiver plug is extra small and is basically hidden on the back of my tower. The laser precision is great in UT3 and and other games. Let me know if anyone has a problem with their mouse. I've been using this almost 9 months now and it still feels as new as the day I bought it. Oh yeah, the scroll wheel is amazing fast too, you can really get a workout flicking that S.O.B.
