This is the correct way to wire it!
Works great so far. I have it wired to slow down a 24V motor. I realize there is no wiring diagram included and most negative reviews are probably because it's wired incorrectly. I've included a diagram in my pictures to wire the controller properly. It doesn't even get warm when using it, hope this helps.

12 volt NOT 24V
Worked great on a 12 volt 80 watt fan.....when i put it on a 24 volt 80 watt fan it burned up immediatly

Works well on 12 volt / 80 watts, would buy again
Heck of a job Brownie! Nice little speed controller, I'm using it for an aftermarket heater in a tractor. It was cheaper than a switch at the auto parts store. Doesn't heat up on an 80 watt / 12 volt motor, it's only been in use a week but it feels well made and is certainly worth more than the price. I attached it to the case with double sided foam, there are no real attachment points otherwise. I would buy again. The wiring guide in the product photos was accurate.

So far so good
no instructions, so had to spend additional time figuring out. Other than that so far works fine.

Easy to install- easier to use
This is a great add on or replacement for RV bathroom fan control. We installed a larger electric motor that was a bit much for our RV bathroom fan control- this device was the perfect answer to adjust the fan speed. It also has a positive OFF setting. Great item.

Ok for a start
Gets super hot. Worked for a little while but lost confidence in it.
