Razer Mamba 4G-6400-dpi

very good grip. Very convenient the fact that we can plug this mouse as a wired mouse, like this, when the battery is empty, just plug and go just to play. Very good performance in wireless mode, I did not realize the difference with a wired mouse playing a fps as battlefield 3 for example. I confirm the 12 Hours of autonomy in wireless mode, by turning off lights mouse recess. Very good gamer mouse.
