I don't see myself using the caps lock disable much, but the win key disable is a godsend. F11 apparently switches the windows/alt key functionality...for reasons which I can't figure out.
test, they are the same OEM as Filco, costar, so build quality is the same with a few differences in features. First off are the obvious Fn media keys and the dedicated shortcut keys, also, Filcos use ABS plastic for their keycaps, Ducky uses lasered PBT. Unfortunately, at the moment, there is no tenkeyless version >:
Once I put the board through some heavy use I'll probably throw up a full review.
