Cool Mouse for its price. DPI can be up to 32000 customize. Buttons click clearly, not very loud, the sub-lid works, but, as always, it's crooked. The application for setting up is uncomfortable, but with this you can accept. You can also configure macros. In general, a good wireless mouse.

It seems that everything is fine. There are claims for the quality of plastic, it hurts cheap and a little nasty to the touch, we will look at work. Now everything works properly, although they say that the encoder wheels very quickly fall off.

The mouse is cool. Conveniently lies in the hand. To the touch everywhere plastic, softach No. Works well. On a plastic rug sometimes stands. Weight, with all the canopy is felt massive. The buttons are pressed gently. Side buttons are clearly under the thumb. I like everything so far. I have a brush not more, but the mouse lies well
