Came a mouse for 2.5 weeks in the Ulyanovsk region. The box is a little crumpled, but inside the mouse in the navel-there is no damage. Works well, and the backlight is basically uniform. Suitable for those who have a large brush. What about color settings-as far as I understand the color can not be fixed (at least without software, I do not know where to download it if possible), and constantly changes. It's not critical to me, so it's okay. Earlier 1-1,5 years ago already bought a similar mouse (in the photo there is for comparison) black and it works properly. Nuance: The black mouse has a cover of the body (dark parts) soft touch, the white mouse has a gloss. The mouse is very good, take it and do not stop.
