1) This, of course, I missed powerfully, but where should I put my two extreme fingers? They crawl on the rug with the mouse, ah-ah-ah, Logitech.
2) I don’t know about you, but the sniper button had to be made programmable. Why do I need it when there is already a very convenient DPI switch? Okay, now cyber cutlets will come running, who will say, they say, "Well, you're running with a gun, shot back, got a sniper and you have no time to switch to the very bottom" - blah blah blah, and then when you need to pull out the gun, you don't need to switch the sensitivity up will?
Well, in addition, I'm not for shooters, I just would like it to be programmable, I would put some other action there.
3) The socket, which can be opened to get to the weights, is somehow suspiciously easy to open. I can't say that it is "broken", but one strange minus may follow from this - for some reason, when you need to make POINT mouse movements, sometimes it seems to hang and does not react. Whether it's a problem with the mat, or with calibration, or with the settings, in general, I don't know, but the mouse is definitely inaccurate in minimal movements, and I haven't figured out why.
