Total downgrade + boorish attitude of the company to the buyer, their programmers are not even going to work with the problems that ALL users write about for a year. Money received - do not care about the rest. It is impossible to use this keyboard normally - constant juggling and reconnecting with volume jumps is not a normal operation! To hand over such a miracle back to the store, alas, will not work - glitches are caught in the process of use. I just want to throw it away. And this is for such money! MX Keys is not my first device from Logitech, but it definitely became the last one.
