Completely rewrote my review after a week of use. In general, the mouse made a positive impression, already starting from the packaging, and would have been five plus, if not for the software. Very nice matte plastic, does not leave prints. The hand is comfortable. Properly selected weight, not intrusive lighting. I bought a mouse for Eve-Online, I got used to the side buttons in 4 days. I don't regret buying it and I recommend it to everyone. A very good mouse for the money, but the software is already trifles.
