I bought a Razer mouse and the software was absolutely awful. It was the worst mouse I have ever owned and I will never buy another product from those incompetent idiots ever again. The software problem was a well known and documented problem with Windows 7 and after over a year they didn't even try to fix it; lazy incompetent assholes.
I bought a Logitech gaming mouse for half the price and not only is it every bit as high quality as the Razer mouse but it also works flawlessly.

If I have burnt my bridges I will walk on water.
If you're on the shore, then you're sure not me, oh
My seething wrath and urge for blood is fueled by searing hate.
I'm X X X bitch, triple X rated.
