The Razer DeathAdder Essential is a wired gaming mouse that keeps the right-handed ergonomic shape the DeathAdder line is known for. A 6,400 DPI optical sensor handles tracking, and five programmable Hyperesponse buttons let you set up actions your own way. Razer mechanical switches are rated for up to 10 million clicks, and the logo and scroll wheel glow green. At 96 g with a 1.8 m cable, it measures about 127 mm long by 73 mm wide, a size designed with long sessions in mind. The body is shaped for right-handed use, so it is not a mouse for left-handed players. This is a new, boxed accessory.
