The Deathadder Elite uses a 16,000 DPI optical sensor, but big numbers don't necessarily mean quality. Here's the important bit: for the Elite Razer chose a sensor based on the PMW-3389 developed by sensor company Pixart in collaboration with Logitech, which is easily one of the best mouse sensors available with 99.4% resolution accuracy and a 450 inches per second, or IPS, rating (how fast you can move the mouse before it loses tracking accuracy). Razer's implementation should deliver flawless tracking, even if you move the mouse as fast as you can. For the majority of games and gamers, the Deathadder Elite is an amazing mouse. It’s simple where it should be, with two perfectly placed, generously sized thumb buttons, has a great optical mouse sensor that will work on both hard and cloth pads, and has the ultimate body shape for a claw or hybrid claw/palm grip.
