In my review, I tried to fully describe all the pros and cons of this device, identified for almost 3 weeks of intensive use. With all this, I would recommend it for purchase, as the keyboard is absolutely worth the money (in my humble opinion). I hope my review has helped someone. Good luck. Has some pros: 1) Optical mechanical switches (in my case, red, without clicking and tactile feedback). 2) Aluminum case. The polished surface looks nice and is less easily soiled. 3) Skeleton (rather not a plus, but an amateur. But I like it) 4) Full color RGB backlit keys with preset profiles. Both English and 2022 layouts are highlighted. 5) The keyboard is really heavy and stays on the table like a glove. You can hardly move it with your finger, accidentally moving it will be extremely problematic. the legs are glued to the table, pressed down by the weight of the keyboard itself. 6) I did not notice any special backlash or creaking of the keys. The space does not stagger, from the word at all (which cannot be said about some competitors for 9000+). 7) Excellent moisture protection. The main thing is not to spill the sweet (although you can then rinse for sure). 8) PRICE. The reason why I put 5 points, not 4. The price crosses out all the minuses. About the cons below. Some cons: 1) The main drawback of this keyboard is its SOFT. If you can call it software at all. Creepy, horrible, with constant errors when trying to save profiles. You just need to take this software for granted and come to terms with it. 2) Profiles and backlight brightness can be switched both without software and with it (without software, the choice is much poorer). The problem is that the keyboard in some cases does not remember the selected backlight profile and resets it to a rainbow wave upon reboot. In general, you have to dig. 3) Red switches. Their plus is a relatively quiet operation (I took it because I don’t like the clicks of blue switches). But this is their main disadvantage. I have been using the keyboard for more than 2 weeks, and I often hit the F button without noticing it myself, since the keys are pressed very easily and without tactile feedback. I really hope it's just a matter of habit. 4) The backlighting of the keys is located directly on the board, in connection with which there are flashes between the buttons and the light goes up the keyboard, slightly illuminating the bottom of the monitor (not noticeable in games, but still). In newer versions, the backlight is already built into the switch, which is much better.
