Thanks a lot for sharing. I used to go on /r/MKB a lot a few years ago, but I had to stop because I wouldn't ever be able to afford such nice-looking keyboards, as they were usually so expensive :(
I'm not even going to try justifying the cost based efficiency or ergonomics or build quality, I simply love the sound of a well-produced mechanic keyboard.
If you look at his channel, I was listening to his keyboard though via his C++ tutorials
