In general, the impression of the mouse is very positive, not a bit sorry about the purchase. ( 4500 at the time of review ) If the mouse were made more qualitatively in terms of assembly, they put a normal wheel, normal side buttons, etc., and raised the price by 500-700, it would be the best mouse for its price! Got pros: Fits perfectly in the hand (I have a really big hand) Sensor gun, don't rip it off for anything The software is quite good, the main thing is to figure it out and everything will be good The battery holds a charge for a very long time! Cons: The build quality is just sad, the buttons are loose, the wheel makes clicking noises when scrolling. Also, after a week, LMB began to backlash up and down, it does not affect the work in any way, but I personally do not like it.
