Very nice feeling linear switches. They are very smooth and have excellent crispness tactility on bottom out and return. Acceptable light transmission for not being clear topped or having a diffuser.
Perhaps the most interesting aspect is the sound, which I found to vary greatly depending on the board they are in, far more than usual. They aren't as sharp as something like a HXM Xinhai or Feker marble white and accentuate the hollower "thock" sound, but aren't what would be considered a traditionally "thocky" switch. They honestly sound incredible and are very fun to play with in various configurations. I swapped the stock springs out with some 63g dual stage springs and had then in a Yunzii AL80, but I found them a poor fit due to the acoustic inconsistencies of that board, combined with the Snow Grape's very long, nearly 3.9mm of travel in what was my primary gaming board. Instead, I popped then in a Weikav Nut65 with an Aluminium plate, and the sound is beautifully mechanical without any harsh notes.
Overall, very nice switches and are very fun, but be aware of the 3.88mm of travel. Comparable to Xinhai heavies, but with a wider, more complex sound and slightly slower.
