The Razer Viper possesses one of the most advanced optical tracking system of any mouse to-date. This is a high-precision, extremely accurate input device that operates at anywhere between 25 to 150% more resolution than other optical mice.

Razer mice have always been known for the ultimate in increased sensitivity. We believe that the Viper is the best mouse ever made for high sensitivity players.

Roughly 70% of the avid gamers in the world play their favorite games at medium to high sensitivity settings, and this mouse was made for you. For those of you who play and compete at low sensitivity settings, we do not recommend the Viper mouse.

If you are not certain what type of player you are, our definition of a lowsens player is one who plays at ultra-low settings and moves their mouse on their mat at around 50 inches per second. If you are one of those low sens players all is not lost ... Razer is hard at work, burning the midnight oil, developing a future model that will more than adequately support your style of play.
