I just received a set of KBDFan's Topre silencing rings and their engraved POM keycaps. I installed a set of the rings and the keycaps on my Type Heaven the other night, and the improvement is nothing short of amazing. I had previously bought a silenced Realforce, but I didn't care for how mushy the outer keys were, and I sold it. I did enjoy the relative silence, though. My Type Heaven is now extremely quiet with no upstroke clack at all, just a muffled thunk, and since it's a uniform 45g keyboard, there are no mushy keys. The worst thing is installing them. I turned on The Last Jedi when I started the job, and I finished it around the time the movie ended. They went on relatively easy, but with nearly 40 screws to remove and the need to unsnap every stem, it's definitely a labor of love. I'll be doing the same job on my Realforce RGB in the near future. The Type Heaven is my office keyboard, so I was a little more anxious to silence that one. I can safely say it's now quieter than any of the Logitech and HP rubber dome keyboards that are in use around the office.
I don't have a lot to say about the keycaps except that I was impressed with how cleanly the markings are engraved, and the finishing of the caps is great. They have that slightly slick and shiny look that Cherry's G80-3000 black keycaps have, but of course the markings are much harder to read since there's no infill. The only disappointments are that the space bar is ABS (mentioned on KBDFans's website, so that wasn't a surprise), the Windows logos are the old '95 versions, which are more dated (or retro) looking than what Topre uses, and one of the Alt keycaps has some weird white marks that won't come off. I'll have to email KBDFans about that and see if they'll replace it. Other than that, if you like POM keycaps and don't need to clearly see the legends, these are great.
I haven't posted any pictures since the ones on KBDFans's website are pretty good, but I can if anyone would like to see something in particular.
