These are some of the nicest feeling keycaps I've ever used. I wasn't sure I would get along with the taller profile, but I like sculpted profiles, and these keycaps work very well for me. The fit and finish is one of the best, and you can tell that these were made in molds designed for PBT. They have some of the cleanest, straightest edges, and they look really nice on my keyboards. Since I've gotten these and built up two keyboards and a macro pad with them, I always look forward to typing on them. The scooped keys are subtle, but after a few hours, I had not trouble with them at all, and I prefer them now.
