The Razer Mamba Gaming Mouse is an ergonomic wireless gaming mouse that frees you from the corded shackles of a mouse hooked to a computer. The 1ms response rate and 4G dual-sensor system ensure that your gaming abilities and speed will improve a lot. The laser and optical sensor automatically calibrate the mouse for any surface. Put simply, you’ll be the one doing all the fragging even if you and your opponent click at the same time. You can use it in wireless mode or with the USB cable, which will automatically recharge the Razer Mamba’s battery and allow uninterrupted gaming round the clock. If you’re taking a break, dock the Raxer Mamba into the charging dock that also functions as the wireless receiver.
