You'll like the DeathAdder quite a lot....

The DeathAdder is easily our favorite Razer mouse ever, and is in contention to displace our G7 as our favorite gaming mouse. Though lighter than we're used to, and wired, the silky rubberized surface, comfortable curves, and extremely responsive mouse buttons leave us in no hurry to return to the G7. Many of these issues involve a degree of personal taste, but if you're like us you'll like the DeathAdder quite a lot.

Your brain and the game is all that's left.

"It just plain feels right in the hand. It's comfortable, weighted right, and easy to press every button without accidentally hitting the wrong one or slowing down to think about your precise finger placement. You just put your hand on it, the mouse disappears, and the connection between your brain and the game is all that's left."

Top Performer in MouseScore 2007

"Razer's new mouse is the top performer of all gaming mice we have ever tested. The DeathAdder blows away all competition in the ESReality Mousescore 2007 rankings. With these results to back it up, it would be fair to say that no mouse you can buy today comes close to matching the incredibly performance of the DeathAdder. To top it off, Razer have packaged this incredible mouse in arguably the best looking body."

Being the best in gaming mice...

"Being the best in gaming mice is where Razer has earned its reputation, and they continue to work hard on staying number one with each new mouse. The Razer DeathAdder is their most recent mouse to help retain the throne."
