There's genuinely not one thing I can say I don't like about it. The fit and finish, the style, the ergonomics, the function. I've been a Deathadder devotee since 2008, and only just bought this one because my Deathadder 2013 Edition finally went to the big gaming mousepad in the sky after 6 years of service. Overall Review: Razer and their products have been the topic of numerous heated internet debates and I won't say that they don't deserve at least some of their negative public perception, but if they do anything right, it's the Deathadder.
