Have been typing on my RF87UW 55g with a PBT spacebar since last Thursday. It's amazing. I also own a HHKB, dental band modded, but RF feels superior. Best feeling keyboard I've ever typed on in my life. Too bad I couldn't get my hands on the black one though, but they ran out of those at MD pretty fast.
I noticed that every stabilized key, aside from the spacebar, has some sort of rattle? Can I get rid of this by applying some lube to the stabilizer wires?
