The order in new year's days came quickly enough-a month. The mouse corresponds to the description and even better. In the description of dpi 10000, in fact 4000. The polling frequency is 100 hz, in fact immediately out of the box without drivers 500 hz, after installing the drivers 1000 hz with the inclusion of the frequency 1000. The color is pleasant silver metal, the backlight is soft and not full. Satisfied completely! Thank you seller!!! I recommend to everyone! I want to share my experience for those who are in the "tank". Mouse game and i think everyone take it for games, so i want to share the settings profiles for the game world of tanks: out of the box the smallest resolution on the red backlight will be 1000. With this resolution, aiming will be difficult. Just put the driver from the disk that came with the mouse and create your profile-for example games and set the resolution for red 300, blue 500, green 1000, the rest can leave, and you can again in a circle duplicate. Frequency can be 250 put (but does not affect much and 125 copes). Save and use. On the red backlight with 300 dpi aim will be very convenient. More than 1000 dpi in this game in principle do not need. All with acquisition and good luck!
