The kit includes 8 keys to replace the game buttons, I have not installed them yet. Pros below: I have long wanted to try the mechanics, but did not get around to it. And then there were just promotions on the market, so it turned out to take this model on red switches for 2400, which is simply nothing for mechanics. What can I say - so far it's super unusual after the membrane (activation of the keys with little effort halfway), but I already like this quiet tapping of the keys when typing. I really liked that the backlighting of each key is configured separately, you can leave some without backlighting. The keyboard sits very well on the table - it's hard to move thanks to the rubberized inserts. Good software with profiles and macro settings. The classic layout of the keys, except for the fact that the printscreen group is shifted to the right instead of indicators (I don’t know why). In general, I think when I get used to the keys - it will be generally super. Some cons: Due to the fact that the diodes are at the top of the keys, the manufacturer placed the 2022 letters in the 1st row with the English ones, this is not very important for me, but it will be inconvenient for a person who often looks at the buttons, plus the font is rather poor, but this is not so important to me . For me, a single-row enter is a minus, because I'm already used to a two-row one, but I think this is a matter of habit.
