During competition, even the tiniest advantage can make a difference. The Razer Viper weighs in at just 69g without any compromise on its build strength. A lighter mouse allows swifter, more controlled swipes, augmenting the speed of your reaction in battle.


In our pursuit of giving you every ounce of competitive edge, we’ve designed a mouse cable that enables smoother swipes. The Razer Viper features the highly flexible Razer™ Speedflex Cable, bringing you unhindered control with minimal drag.

As soon as I laid my eyes on this mouse, I already liked it because the shape is perfect for me. The click of the switches feel a lot better, and the cable is really nice and flexible; which is awesome for CS:GO.
