Love these! A few observations after running Yolks for a few days on Neo 65 Core Plus:
- These are somewhat tight in feel – likely due to high tolerances and literally zero stem wobble. Basically, doing some back to back with switches that have similar operating force on paper, they feel a bit heavier to type on – in a good way though!
- They are super smooth and clacky AND have a bit of textured feel / dryness to it – but in a really good way. They are not badly lubed or anything but there's definitely a bit of this "sandy" feel to them – which I honestly absolutely love.
Overall, definitely recommend! When I just tried them, they seemed okish but nothing revolutionary, but after some time I keep liking them more and more.

I love the HMX Egg Yolk switch. Crisp, clean, and satisfyingly poppy clack that makes every keystroke sound addictive.
