Kailh makes some of the best clicky switches on the market.
The Kailh BOX Crystal Pink switches use the same click bar mechanism that the Kailh BOX clicky switches are known for. So you can expect a more stable and thick "double" click. One click on actuation and another click on release. These are heavier than BOX whites, and on paper slightly heavier than BOX jades. However in real world use, these actually feel a lot more heavier than BOX jades. I would say that if you're not used to heavy switches, you may experience typing fatigue quite quickly using these. Definitely not as heavy as BOX Navys, but still, I would keep that in mind when choosing these switches. And this is coming from someone that uses heavy switches regularly.
I don't think you'd be disappointed going with these, but honestly if you're looking for a thick click, I think you'd be more satisfied with BOX jades.
