Ive got a Razer Diamondback and its awsome. it never gliches, looks awsome, and its really sensitive.
In all the magazines ive heard so many complaints about this mouse. Has anyone els here got one and have you had any problems. They say it gliches in quake4 but my mate has finished quake (with his diamondback) twice and its never gliched.
Itd be intresting to see if the reports are true with a larger test saple and with people who know what a glich is.
I have the Diamondback and I love it. I’ve never had it glitch on me at all…sensitivity is honed to perfection with a little tweaking of it’s drivers.
All the pr0s use them 
Haven’t played Quake but I’m yet to have a problem. The only reviews I’ve read have been full of praise for it.
I’ve only heard good things about the Diamondbacks - From what I’ve read they’re fast, responsive and like Waffles said - a lot of pr0 gamers use them so they must be doing something right.
