I had 0 issues with my Deathadder years ago. Other than it breaking after about a year and a half. A bit overpriced and underwhelming build quality, but nothing I'd call terrible. I was thinking of going back to Razer for my next mouse. I prefered the form factor of the Deathadder to my current Logitech G500.
