PLUM owners, what do you think of the quality?
From following Massdrop comments, it seems like more and more owners of the RK version, myself included, have noticed their keyboards developing problems over time-- ghosting, dropped keys, etc. It's really a shame, because the key feel and the feature set are both top notch, especially if you take the price into consideration, but if the thing doesn't function properly, no amount of good "feel", programmability, or flashy lighting effects can outweigh the annoyance.
Anyway, I wonder if the various brands within the Noppoo/PLUM/RK family have different levels of QC. The PCB on my four-year-old Noppoo definitely strikes me as nicer than the one in the RK (and MUCH nicer than, for example, the one in my Keycool *shudder*), but this could just as easily be a generational issue rather than anything you'd see reflected in the brands now.
