Intuitive ergonomic design Since its first inception, the Razer DeathAdder continues to offer gamers the most comfortable gaming experience ever. Its contours and curves are perfectly designed to fit snugly under your palm, or control just as well with a claw-grip.The mouse is designed in a matte black finish that prevents sweat build-up and promotes better grip 6400dpi 4G optical sensor The all-new Razer DeathAdder is equipped with a 6400dpi 4G optical sensor – the highest native DPI optical sensor available on any gaming mouse today with zero interpolation. It is capable of mouse movements of up to 200 inches per second and 50g acceleration, meaning you can move it at either fast or slow speeds, and it will always respond onscreen with exacting accuracy and the organic fluidity only possible with an optical sensor.The Razer DeathAdder’s sensor is also capable of tracking Z-axis to as low as 1mm on most surfaces. This is perfect for low-sense gamers who can then set tracking to cut-off as soon as they lift their mice, ensuring consistent in-game control all the time. It’s all in the Mouse Click No other mouse clicks as sweetly as the Razer DeathAdder. We spent hours designing the fulcrum over which the two large main buttons sit, with the perfect bounce back to your fingers – providing absolute assurance that you’ve actuated the switch beneath. The click force required is also extremely low so it’s almost as if all it takes is you thinking it, to make the mouse respond instantly. Give the Razer DeathAdder a go, and you’ll click the difference.Better Grip, Better Play We discovered that as a highly favored mouse of many pro-gamers, what they loved about it more than anything was its snug fit to hand and intuitive button placements. With the latest iteration of the Razer DeathAdder, we added rubber-textured side grips so whether you’re a low-sense gamer who has to lift the mouse constantly, or a high-sense twitch player making sudden, sharp movements, these grips deliver even more active control and guarantees the mouse stays firmly in hand at all times.The weight of the mouse was also of significant consideration in this latest design. Too heavy a mouse would hinder movements, while too light a mouse would make it unwieldy to control. The design of the Razer DeathAdder’s shell all the way down to the positioning and choice of internal hardware culminates in a mouse with the ideal weight distribution, and heft in hand for perfect control.
