Great keyboard! The sound is not annoying, tactile is very pleasant. Backlight lovers - there are a lot of customization options. Pros below: Key travel and sound. Size. Ergonomics. I turned off the backlight, thanks for that too. Cons below: I did not like the PRIME 63 store where I bought it. The box was probably opened, judging by the backlash of 1 cm on the sticker and the remaining air under it. And a few keys have small chips. But again, this is a question for the decency of the store, and not for the keyboard.
