Like I said in the reddit thread: You can get a Filco for that much, why get one of these?
Is the build quality of a Filco really that much more noticeable than that of Coolermaster's QFR, or the Rapid I (which will presumably be superior, and at the very least equal to that of the QFR) to the point where you would forego extra features (which may not appeal to everyone, but can simply be ignored if they are not to your liking) at the same price?
With either keyboard, I doubt that build quality issues will result in the death of the keyboard before some other external factor (such as spilling a drink, dropping something heavy, etc.).
