A very quiet (for mechanics) keyboard, with a full set of keys (except for pause and scroll lock) and even some kind of Cyrillic backlighting (although if 2022 letters were placed higher, then the backlighting would probably be full). Now about the "main disadvantage" mentioned in most of the reviews and reviews - from the wireless interfaces there is only bluetooth. Although I did not experience any delay during operation or disconnections, but what prevented me from adding 2.4 GHz functionality and a penny receiver to an expensive keyboard? Perhaps this would solve the following problem. When the power saving mode is enabled, the keyboard turns off after 10 minutes of inactivity and turns on the longer it was in this mode - from ~1 to ~2 seconds, ignoring all buttons pressed during this time. To wake up faster - you need to press more keys, I just press 321 on the numpad. This mode is switchable, but then, of course, the battery will discharge faster, and it is not very outstanding here anyway. For now, I decided to try to get used to this mode, since a couple of seconds won’t do the weather for me. In principle, I took this clave with the expectation that the Chinese will fuss and set up the production of custom low-profile keycaps, perhaps even with Cyrillic. Or, in extreme cases, I will try to buy redragon anubis with white keycaps and full Cyrillic illumination and rearrange the caps from it. The sizes of the letter keys are approximately the same: for the K5 it is ~ 16.5*16.5*4.3mm. I measured the Anubis, but I already forgot the exact size, but there was also something about 16-17mm. And there, and there cherry mx fastening caps. But the shape of the front side is slightly different, on redragon they are completely flat, which is not so convenient in my opinion. So I'll wait for custom caps first.
