In general, the shortcomings could be put up with, if not for the breakdown in such a short time. I think that a mouse for 7-8k should last much longer. Judging by other reviews, such breakdowns are quite common with this and other expensive models. Has pros: It fits comfortably in the hand, good body materials, beautiful appearance. Different cons: -Glitchy software, settings constantly crashed. As a result, I had to save everything in the mouse itself and remove the software. - Not the longest battery life, given that all the backlight was always turned off. - Noisy wheel, which eventually broke after a year and 2 months. It's good that the guarantee was 2 years - I was able to return it.
