Razer has just updated their top-of-the-line Mamba gaming mouse with several new features and design improvements. The Mamba was initially released back in 2009 with an optical sensor and DPI of 5600. It got several updates since then with an incremental one in 2012, when Razer updated the sensor to a 4G dual laser one with 6400 DPI. Rest of it, pretty much stayed the same. However, now its getting a major revamp and Razer is now calling it the new Mamba; the most advanced gaming mouse in the world.
