All the rules, the form is comfortable, I didn’t have to get used to it, only to the side buttons. Just punish the designer of the legs and everything is ok. With its pros: The form is comfortable, you get used to it right away, there are no breakdowns and other problems yet Cons below: the side buttons are almost flush, so you don’t understand which one you are trying to press (maybe it feels like this after the old mouse, but they were not very conveniently made) the legs of the mouse are specific, and I don’t quite understand where to get them in such a form when they are worn out.
