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

### ⭐⭐⭐⭐⭐ Received what was ordered

### ⭐ 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
*by R***K on July 25, 2024*

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.
