I have the same mouse as the OP. Although, I do like it and don't regret the purchase, I see no reason to get another gaming mouse when this one eventually dies. I'll never be a pro gamer, what do I need greater mouse precision for? It's looks cool and I can control my music player from any program, but not really worth the premium price (though this one is a deal compared to Razer and other gaming brands). Next time, I'll probably get a cheap mouse, but one that has at least one extra button, because binding my push to talk key to my mouse is great.
Aside from that, I have a pair of Razer Carcharias Headphones. They sound good and NEVER become uncomfortable (other than overly warm harms once in awhile) no matter how long I wear them. They have two significant flaws and one fatal. There's a remote built into the cord, which does nothing all that useful except degrade the quality of the line and the mic isn't anything special. It's fatal flaw is that it leaks sound like no other. I have to turn my game volume way down so the mic doesn't pick up my sound and annoy the crap out of everyone on vent. Razer never published my review of them on their site, even if I did give them 4 out of 5 stars.
My keyboard is a cheap one, but reliable. That's about it I think. Oh, wait enraptured reader! I also have a F310 Logitech gamepad and a Tatsunoko vs Capcom fightstick (along with a Wii to USB adapter). Also, some really old wireless Logitech gamepad.
