Umm i can give some more in-depth answers later when i have more time. As a quick overview i can say: i love it, the silencing totally works - any switch i open up gets the little silicone pellet treatment. I finally got my hands on 1mm (exactly) silicone which is juuust barely thicker than the gap below the stem-'stick' thus just dampening while reducing travel not at all:
(thanks to the guy who used the thin sheet for topre)
The tool is indeed a belt hole tool - luckily the smallest of the wheel was just right (i sharpened it a little).
Please be aware however, that you will lose the typical authoritarian knock when bottoming out with plate mount switches. If you're going to miss that - watch out.. also due to the silence you'll start noticing other things like spring ringing, scratching, etc.
Key upstroke now is loudest of course, no way to dampen that.. a thick custom pcb might help in that regard.
If you guys have some patience and don't want to commit with sheets and tools yet, i could make a few packs and send them out.
