Definitely still in the early impressions stage of getting to know these switches, but I put some in a m̶a̶c̶r̶o̶ ̶p̶a̶d̶ - er… switch tester… last night and have been fiddling with them.
So far I concur with what I’ve heard. In my test sample size of 9, 6 feel basically perfect, one feels quite good, one feels a bit tight, and one is definitely too tight, binding on off-center presses and translating friction through the push-feel when actuated slowly. (When typing normally it’s a lot less noticeable.)
These strike me as a switch for switch enthusiasts, but not necessarily for the general public - kind of like UHMWPE stems, but more approachable and with a slightly higher success rate. While a significant number are iffy, the majority aren’t - and those are genuinely impressive.
Those that are up to spec are easily among the top three most smooth stock mx-compatibles I’ve tried so far. Because of the generally heavy lubing, the feeling is somewhere in-between “butter” and “skate” - and these would definitely be all-skate with a thin lube. If you try really hard, you can perceive grain/texture - but as little as I’ve ever felt in a switch. These things look like oiled glass, and feel like it, too.
Much more testing imminent, but so far these continue to remind me a lot of the Momoka Frogs when it comes to the feel of their smoothness, plus the added novelty of being all-polycarb.
