I' ve only had the keyboard for a short time, but I' ve already managed to properly protest everything that' s important to me and also somehow validate it against what people complain about with this keyboard. First, the keyboard doesn' t really have all the keys illuminated. This means that when there are more than one character on the key, only the top is illuminated. Honestly, I don' t consider this to be a problem, because most of the time I type anyway, I don' t look at every extra key. I also went for the US layout for the same reason (also because I heard numerous negative reviews about the quality on CZ/SK from multiple directions, although I don' t know how this is possible), because the accented letters are simply not needed. The USB cable is bifurcated at the end, 1 serves as a keyboard connection, the 2nd serves as a connection between the USB hub on the keyboard and the PC. This would probably be better marked up somewhere, but again, it doesn' t pose any new problems. It' s more of a detail. What I personally have a problem with is that not all buttons are fully programmable. In fact, the only editable buttons are the macro buttons, which is quite disappointing when I' m switching from Razer after years. Not that I would ever use it, but maybe because of that the buttons can' t be reprogrammed to 3 profiles or the gaming button, which I simply don' t use for these functions or maybe only rarely. On the other hand, a 5x3 custom maker or mapping is probably more than enough, you just have to get used to switching profiles. The same question mark hangs over the G-Hub, I already use it for the mouse and headphones, but it is not exactly friendly to the keyboard. I would imagine the backlighting options to be better, and custom solutions are made rather tediously and not very skillfully (again, compared to Razer, disappointing). Apart from that, the keyboard was surprising. I mean, she probably wasn' t directly surprised, 4 thousand is already enough and some quality is expected here. The rubberized buttons are very pleasant, as are the keys themselves. The low profile and open design is very practical in the long run and cleaning. The whole thing is set in metal, which is very pleasantly solved and, above all, matte, so that no smudges remain on it. When playing, I notice slightly faster responses due to the shorter distance the key has to travel to activate. The cable looks like it could survive a nuclear disaster. The legs also look stable. I was worried that the sound wheel would feel cheap, but it also looks like it' s determined to survive enough. In general, I am satisfied with the keyboard so far, it depends on how it will be in the long term. It is also necessary to take into account that the keyboard has custom switches with some regular Cherry switches, but I looked on the Internet to find replacement buttons or even customized buttons for this keyboard.
