I have read about problems with Noppoo's on GH, but from the 2 years I've had mine I've experienced no issues. I do hate the spacebar sometimes though...replacing keys on any mini board is going to be difficult, but a Choc Mini compatible spacebar is just notoriously impossible to find.
I was more impressed with my KC84, to be honest. But...the black pom caps on the noppoo are still to this day my favorite of any cap to type on (for linear and clears).
