The mouse was bought only today, so I am sharing my first impressions and problems, there will be something to add to the review - I will add it during operation. The score was lowered immediately due to buggy software that no longer runs. Before that, I worked with a Microsoft IntelliMouse, which I had for about 16 years and even built an autoclicker into it. Let's see how this one will show itself, but I am completely satisfied with its convenience, size, button position, clicks, size and tactile sensations from the rotation of the wheel, even more than I expected before buying. The weight of the mouse without batteries is 71 grams, with two batteries - 136 grams. For those who are critical of weight, if desired, you can find or make your own adapter for smaller batteries and reduce weight. Well, if you really drive on this topic, then you can disassemble the mouse and drill holes in the frame, as well as from the bottom side, I think you can win 10-20 grams. Well, I immediately ran into a problem that I read a lot about before buying - the "G Hub" does not work, this is not critical for this mouse, but I definitely won’t buy Logitech G935 headphones, because. everything works through it, judging by the descriptions and reviews. I chose between Logitech G935 and HyperX Cloud MIX, now the choice is made and not in favor of Logitech, thanks for that to their buggy software.
