Cougar Revenger S @ TechPowerUp
 

Cougar surely knows how to upgrade properly. A great example for this is the Minos X5 I reviewed in the past. This time around, the Revenger S is on my plate, an updated version of the Revenger; PMW3360 top optical sensor, RGB lighting, high quality main switches—the recipe is there for a truly great mouse.
