Impressions from the mouse are only positive. Problems with pressing buttons are minor and probably related to the style of my mouse grip. my son really liked the wheel - he says that when you turn it, it relieves stress :) With its pros: 1. Incredible sensor accuracy. At the moment (2022), this mouse has the best of all gaming sensors - PMW3366. 2. Very well sits in the hand. 3. Adequate software. 4. The number of buttons covers my gaming needs. At the same time, all buttons are accessible with almost no finger movement. 5. Well, the quality of Logitechs is, as usual, on top. Cons: Unfortunately, there are some problems with the buttons: 1. Maybe this is a problem specifically for my hand and my style of controlling the mouse, but the closest of the side keys is constantly accidentally pressed by the second phalanx of the thumb. 2. You can simply forget about using the mouse wheel - when you try to click on it, one of the horizontal scroll buttons always works first (the wheel of this mouse can be swung right / left).
