I will not comment on the quality of the keyboard construction and switches because we are talking about excellent work. The keyboard is sturdy and heavy, while the Cherry MX Silver switches are soft, with moderate noise, and easy to type on. However, I will comment on some negatives that should not happen in a keyboard that costs 100 euros:
1. The keys (specifically the keycaps) fly off while typing or simply pressing them.
2. The RGB has such a low refresh rate that it resembles a pharmacy sign.
3. The brightness intensity has decreased in some keys in less than a month of use.

Update 05/07/22:
1. Another 3 buttons (their sockets) broke with simple use. Over time, the plastic weakens and other buttons "jump" as well.
2. The keyboard gave me tendonitis.

It is a keyboard with solid construction and Cherry MX Silver switches. It deceives victims in marketing, which is impressive on paper. These people knew how to do that, but they didn't know how to design plastic keys and have no idea about ergonomics. I have been using computers for over 20 years, and getting injured by a keyboard is happening to me for the first time. And I experienced this from the most expensive one I've ever had. Irony.
