I really like these. I have them on a Matias quiet click full-sized keyboard and they're really nice. Recommend.

These feel really nice and tactile. Haven't built a board with them yet but I can tell they have better tactility than mx clear, mx brown, gateron brown, and zealios that I have used on boards. Tip: you can open them up and do some modifications to make them more tactile. Experiment with making the bent metal part less of an acute angle, or making the little legs that the slider has to "click" past at a more acute angle. I unbent the metal part to a 90 degree angle and bent the metal legs to a 90 degree angle, and it feels like I'm breaking a toothpick every time I push it! Probably too much for an actual board but it's fun to experiment.
