Nice Stems, But...
I ordered the Snow Linear Sliders. The quality of these stems (or sliders) is very nice. I am very happy with the smoothness and consistency of these, especially for the price! Other similar products are twice the cost or more. However, there is one significant issue that I haven't seen many people highlight. These stems seem to ONLY work with Cherry bottom housings. I tried to use these to make some Black Cherry Pie (BCP) frankenswitches and was very disappointed to learn that these are not functional at all with JWK bottom housings. I think the stem legs are slightly longer on these, causing the leaf of the JWK bottom to remain actuated even when the switch is not being pressed. If you use these stems in anything other than a Cherry bottom housing, the switch will have significant, unusable actuation problems. TL;DR - If you plan to use these ONLY in Cherry brand housings, these are great. If you plan to use these in any other brand of bottom housing (JWK, Gateron, Tecsee, etc.), stay away from these as they likely will not work.
So smooth even stock and have great packaging!
A response to Ben (Review of Baby Blue Tactiles)
I was surprised to hear compatibility issues with these sliders because I was happily using them in my main board (Stem replacement for WS Heavy Tactiles). I went through a smattering of the switches I had to confirm function. JWICK T1 OK TTC Brown OK Cherry Black OK Gateron Yellow OK Tecsee Ice Cream OK Gateron Oil King OK 43 Studio RARA OK Kailh Brown OK Akko Lavender OK C3 Tangerine OK Haimu Pastel Mint OK (but feels gross) Melon Milk OK DK Monochrome Onyx OK Maybe it's something to do with the design of the Slow Linear Sliders, or the linears in general, but I didn't find any actuation issues with the Baby Blue Tactiles. They worked in all the non-box lowers I tried. Single presses and long presses were fine and there were no ghost actuations. Anyway, about the Baby Blue sliders themselves, they're pretty nice. A bit more prominent bump compared to browns, vaguely less sharp than T1s. I personally prefer 4mm total travel, but 3.7 doesn't feel too bad either.
