They aren't terrible but no where near the sound profile I was expecting and the feel was off. Also had some issues getting them into my plate/ hot swap pcb. I could see them working out for a plateless build as long as your soldering.
I like these a lot. A little heavy for me, but the feel and the sound is really good and I definitely want to build something with these switches soon.
When they work these are great switches, but they have a WILD failure rate.
I built out a Drop Shift kb with these and enjoyed the hell out of it until the switches started dying: double clicks or non registering strokes. I've slowly replaced them as they've died, and now after ~2 years I have 2 full 35 packs of bad switches.
At the end of the day, it's a good experience until it's not... And then it's awful. Nothing breaks your flow worse than all of a sudden not being able to trust your interface.
