dingumf, chill out. Just because your specific product might not have lasted doesn't justify that the whole Company is crap. Mass produced products doesn't guarantee that what you're getting is going to be perfectly produced (and this shouldn't even come to mind when buying anything considering the chances of actually getting a poorly built product)
I've had my Deathadder for a couple of years now, and I've had 0 issues with it. None of the parts have worn down, and it plays just like new. There's no reason to shoot your mouth off like a child because you might have had an unsatisfactory experience with Razer.
I'm going to say that I've never had a piece of Logitech equipment that has lasted me more than a couple of months. I've bought a few headsets, and mice from them, and none of them have lasted longer than 3 months, and the product wasn't all that good for me to begin with. It's just a preference, and I would have eventually gotten used to the mice, but I wasted a bit of cash investing in Logitech. After I got a Razer I've stuck to them, and even bought a Razer keyboard, and both have been performing fantastically.
Guys, the Deathadder is an AMAZING MOUSE. For me, Razer has been a solid company, especially in comparison to Logitech. At least give them a shot.
