In the past, I have compared some of the best mice in the industry to Razer's DeathAdder. No matter the competition, the DeathAdder always holds its own. Recently Razer decided to give the DeathAdder a slight renovation with a 3500DPI sensor update. Considering how much I've loved my DeathAdder let's hope they didn't mess with the winning formula!
