Been using a QPAD MK-85 with Cherry Red keys for at least 5 years. Never once let me down in all this time which I've never had with any other peripheral in 21 years pc gaming. Only thing I didn't like is after a couple years the rubberised surface on the casing and wrist pad (not keys) starts to degrade and becomes a sticky dust trap. I finally took apart the keyboard within the last 12 months, washed every key and went to town on this deteriorated coating with my wife's nail polish remover to get it all off. Good as new again.
