Frankly surprised by such quality for such a price and from such a company - shame and disgrace. I’m bringing it to change, I’ll try the same one - maybe I’ll be lucky and I’ll get a copy without marriage (naive) : changed to the same. The term of use is about a month. Double-click has appeared 1 time so far (it seemed possible). This one has more effort to press RMB. Raised rating from 2 to 3 Pros below: Holds a charge for a long time (about 3 days with an average game, 2 days with active, charging about an hour) Ergonomics Adjustable weight Good performance on surfaces (no false positives) Different cons: Scroll is TOO loud. Togo and look, the neighbors below will knock what would be quieter. It feels like they put a ratchet there on purpose, as they used to put on bicycles so that the whole district could hear how you ride Scroll x2 - the notorious 4d scroll. Yes, I knew what I was taking, I knew that he was here. I had mice that cost 10-12 times less with 4d-scroll before and it was terrible there. But we take the mouse for 9k and . we get the same terrible 4d-scroll - the wheel staggers, pressing the MMB, you have to make an effort to keep it in the central position, which is why clicking on the MMB always turns out to be strained. To be honest, it would be better if it didn’t exist at all - I can’t imagine who needs it among gamers. Scroll x3 - after 2 months of use, a slight metallic rattle began under the scroll, as if small metal plates were beating against each other. Heard when clicking, scrolling, moving the mouse LMB double click - and this problem did not bypass me. Over time it became more and more RMB (subjective nit-picking) - too easy to press - the weight of the finger is enough to trigger the click - it is impossible to hold a relaxed finger on the RMB. My fingers are not huge, no.
