The all-new Razer DeathAdder has been upgraded with the world’s first 6400dpi Optical Sensor. Achieve high levels of performance while retaining the feel of the optical sensor most DeathAdder users have come to love.
Retaining the same right handed shape of its predecessor, this incarnation of the Razer DeathAdder improves upon the ergonomics by incorporating new rubber side grips. Your fingers stay firmly in control of the mouse no matter how aggressively you swipe.
Razer Synapse 2.0 enabled
Razer Synapse 2.0 is cutting-edge, intuitive, proprietary software that functions as the Razer DeathAdder’s brain, automatically syncing the gaming mouse to a cloud server to download driver and firmware updates, as well as to save your individual settings without you needing to lift a finger. You’ll never have to set up a new mouse at tournaments again when Razer Synapse 2.0 downloads the personal settings from your own Razer DeathAdder, and ports them to the new mouse, making it an exact replica of your own. - See more at: http://www.razerzone.com/gaming-mice/razer-deathadder#sthash.5FJyGxGs.dpuf
