Everyone is happy so far. I advise you to buy. The price compared to competitors is more than good. Replaceable mics are a huge plus, and in theory a mouse for 10 years of work (I would like to believe, but it's hard to believe). All in all, we'll see how it goes. If there is a problem, I will ate the review. Has some pros: - Connecting both via bluetooth and 2.4. Very convenient, I connect to the PC via 2.4, and to the laptop, if necessary, via bluetooth - Working hours. Basically I use 2.4 connection to the maximum. Keeps about 3 days. - Interchangeable microphones. The last mouse ss sensei had to be changed due to a breakdown of the PCM (it worked for 6 years). I bought this one because of the interchangeable mics, because this is the main problem of mice and over time they break down for everyone. - Sensor. Works on almost any surface. Doesn't crash in games. Well, for work in general, fire for such a price - Symmetrical, that is, for left-handers and right-handers. Side buttons on magnets and instead of them you can put plugs Has cons: - The software is not the best. Requires an administrator at startup. The mouse does not store macros, but it does store profiles. - In windows, the mouse is generally defined as a gamepad until the problem is solved, but this does not interfere with work. Only in games, if the mouse went into sleep, then after exiting sleep some kind of game happens and you have to restart the game - The back panel is on magnets and is sometimes removed when the rollers are sweaty, you get used to it over time, and it doesn’t interfere so much. I think this can be fixed with double-sided tape, but I'm not going to do it.
