Improve your gaming skills with the Razer Deathadder gaming mouse. This computer mouse is the first in the world that has a 6400dpi optical sensor. The 4G sensor works perfectly with any of the Razer mouse mats available. Calibrate the sensor on your Razer Deathadder mouse by either using the manual calibration mode or using the mouse mat in Synapse 2.0. The Razer Deathadder has been ergonomically designed to improve your gameplay. The side grips are made from rubber, ensuring that you stay completely in control of the mouse despite how aggressively you use it. The fibre cable is 7 metres in length, so you do not have to sit too close to your computer screen. It is compatible with both PC and Mac computers, and the gold plated USB connector ensures data integrity with data transfer. Also available is a Razer Deathadder gaming mouse specifically designed for left-handed game play. For precision and comfort when playing, buy a Razer Deathadder gaming mouse from eBay.
