What kinds of flaws are you noticing?
3mm plate, no pcb, so the switches are hardly held down. They are, however soldered together by wire, so for majority of the keys, it's not an issue, but the backspace key has a whole column by itself, so if I press it on the side, it's prone to jump up. It's not too bad, though, as I can still easily use the key, and pop it back in with a single press.
