I read reviews and reviews, bought . 1 minus: it is for small and medium palms. It turned out to be too small for me (my length of the palm + fingers is 19.5 cm.). But, this is subjective. Everyone has different grips. Cons: Terrible cable. Its length is enough, but it is hard, crumpled, pulling the mouse along with it. And it looks like a cheap, Chinese craft. With cable, the styles remained somewhere in the last century. 3 minus: scroll. Crunches, rattles and skips cutoffs when scrolling down. Scrolling up is bearable. 4 minus: the price. Moreover, it became a pity for money only when he revealed points 2 and 3 . Pros in general: excellent body material, very cool. The mouse is nice to hold. Cool click sound, LMB a little louder. Super sensor, excellent software (however, after installation, for some reason, the shortcut on the desktop, Win 10, did not register). I don't use the side buttons. My final opinion: this generation of sensei was ruined by bad wire and scroll.
