The new Razer Mamba returns with an ultra-precise 4G Dual Sensor System, that makes use of both a laser and an optical sensor to enhance tracking precision by calibrating to different surfaces and allowing adjustment of liftoff tracking distance. With up to 15% improved battery life for more untethered gaming enjoyment, a new multicolored LED for personalization, and outfitted with an industry-leading gaming grade wireless technology, the Razer Mamba is still in a league of its own.
