I got a little scared when opening the box, as some keys had visibly fallen. I was however quickly reassured by the notice that was also in the box: this was perfectly normal, and I just had to put them back into place.
Now, as for the keyboard itself, I must say I am very satisfied, both with the build quality and the feel: my cherry mx blue boards now feel like cheap toys in comparison.
However, be aware that the noise this keyboard makes might be too much if you like quiet ones, as this might be the loudest thing before an actual typewriter (it's far from being as loud, but still... I'd say about twice as loud as a standard cherry mx blue board).
One fault though: the right windows and altgr keys are reversed. Not much of a problem with autohotkey, but still very disorienting.
All in all, I am still very satisfied with my purchase, and I would recommend getting this keyboard if you want to feel the keys and flood the room with a satisfying click clack noise when you type.
