After 11 years on the Microsoft Sidewinder X6 Keyboard (which is still working successfully) periodically there was a desire to see "what's new on the market?"? And so, there was a need to organize a workplace based on the MacBook Pro. In the old keyboard, the F-keys simply did not work in MacOS (although everything works perfectly on Windows), which I quite often need to work with. Yes, and constantly poke the wire between a stationary PC and a USB hub twice a day pretty annoying. Therefore, it was decided to look for a universal wireless solution, which this keyboard is. I studied the reviews for a long time, I saw that this is a compromise solution. But there was no longer any desire to hunch over a laptop and therefore took MX Keys. Docking with a stationary PC on Windows through the Unify adapter does not cause problems, the necessary software is installed automatically. Connecting via Bluetooth to MacOS is not entirely intuitive (because it didn’t work out of the box as written in the instructions, you had to hold down the search button, and not just turn on the device). In addition, I took an MX Anywhere 3 mouse, it works on the same Unify adapter with a keyboard (sometimes it gets dull, but there are no problems with the keyboard). When working via Bluetooth, both devices also have no problems. Switching between mouse + keyboard devices "by one button" according to the comments works fine only with the MX Master 3 mouse, with mine you need to switch separately, but it's not difficult. I don’t use the backlight, without it for a month of work it took about a third of the battery charge. For games (after the gaming keyboard) it’s so-so, it’s more of a working tool. But, the recesses increase comfort. In general, a worthy purchase. If we still had it in the ANSI version, it would be just perfect.
