The switch works and feels great right out of the box. Sound and tension for key presses is snappy and feels good while typing/gaming. It may be a little firmer of a feel compared to what others may be used to.
UPDATE (1-year use): I've had to switch out a number of switches on specific keys because they've started to double press or not register the key press at all. It's not the keyboard or the board because once I switch back to a different brand of switch the key works fine and consistent. Thus, unfortunately I wouldn't recommend these switches based on their longevity.
Bought this switches as my first tactile switches. I’m used to using linear, but this are so nice. Paired then with the zoom 75v3 and they sound like marbles
I've bought a lot of gear over the year from Massdrop, and always hhad (hey look, a double press) pretty good experiences with them. This wasn't one. The switches feel great and sound lovely; they've also been failing pretty consistently since I've bought them. Some switches stop responding, some have double types, sometimes they're helped if I clean them, sometimes not. I've switched back to the keyboard I installed them in, and after a few months of fuller use, they're dropping like flies.
My expectation with Drop was always that they'd make things right, too, so I didn't sweat it. I'd use them as best I could until they were unworkable. But now customer service is refusing to replace them as they're out of warranty (turns out if they doesn't specify a warranty, there's a strict 1 year warranty, even on products they've made).
I think it's worth making it clear: don't expect Massdrop to make things right, even if their product is failing, even if it's a product they designed and built. I won't take a risk with their products in the future.
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.
