It's kind of hit or miss on the first one you receive, my first Lycosa was terrible, but after I sent it back they gave me a fantastic one, I've had it for probably three years now and there have been no issues.
I also bought the DeathAdder, the only issue was that I wasn't used to it, now I love it.
And the mouse pad, well it's kind of hard to screw that up.

But, of course, this is coming from a Razer fan boy.
