Query: Buggy

I've had this mouse for a while, and I have two major problems with it.1) It doesn't work properly on most surfaces. Any surface that has any sort of red tint or any kind of dark surface it seems to dislike. The pointer will jump around randomly because of this.2) The mouse will occasionally click twice when you only click once. This causes you to accidentally close windows you didn't want to and open files that you dont want to. It is very frustrating.Other than that, I like the design. Any smaller would be too small I think. The bright blue LED is a bit obnoxious though. If I were you I'd drop down a few extra bucks and get something decent.
