Received what was ordered
Works pretty well. No unexpected issues so far.

Blew up within an hour
Used these for 20W fans. Both of them blew up within 5 minutes of each other after an hour. Probably fine if you want to run at max speed the whole time but around 15-40% they just die.

Works great
I used these for some custom fans that repurposed some old PC fans and they work great! The heads on the lugs are a little soft so don't over-tighten them because if you cause your screwdriver to cam-out it is pretty easy to start damaging the head. I also like that the LED indicator only comes on when passing power rather than always being on.

Nice and small PWM controllers
These PWM speed controllers work well. I like the size of these controllers, though I don't think I'd trust them with a sustained 5A load for any extended period of time. There's a couple of holes for mounting options on the PCB itself, as well as the nut and washer on the knob itself.
