My first naga died out of warranty. Bought another.
It's worth it, stop crying just cos something broke, **** breaks... its just childish.
My Cooler Master Seidon died, replaced it.. my Cooler Master keyboard broke, guess what? Replaced it.
Stuff comes with warranties for reasons. Going "OMG X COMPANY SUCKS NEVER BUY AGAIN" is just pathetic really.
Nagas are prone to breaking, specifically the mousewheel being the most common issue (also mine). So far I've had no issues with my current one and it's just over a year old (and again out of warranty), I'll buy another one when it breaks.
