FWIW I have a KeyCool 87 with MX reds (actually typing on it now).
It has been rock solid since the day I bought it. It is a white one, and it really is whiter than white, which makes a really nice base for some keycap sets (in contradistinction to the black of gray cases on most of my other keyboards).
The keycaps are great, although the legends are ever so slightly inconsistent, although that doesn't really bother me.
