I just got a new Naga Pro four days ago and it was also defective out of the box.The mouse doesn't lie flat on the mouse mat.The damn thing behaves as if one of the PTFE feet is the wrong height and rocks back and forth when you use it.I'm still waiting for a response from their customer support.Don't buy one.
Razer is so overrated. So many ppl complaining, makes me wonder how long they will last on cheating ppl with promises of premium hardware and crap inside. I had older Razer naga and in middle of mythic dungeon it began shorting out usb port and any other I have tried. It was barely 3 or so months old ...And worse part is that my warranty was refused and I was caring about mouse so that it looked like brand new...I love the idea of Naga mouse but Razer just doesnt care for quality of their products which is sad. Just too much ppl buys their crap, if ppl would stop buying then they would be forced to raise quality.
