I used this to control fans on the back of my RV refrigerator. I used real estate in a big empty space behind the fascia, tapped the 12v coming into the fridge, and ran to back of fridge through a passthrough. I used a piece of an e-toothbrush cover to make the light visible throgh a hole in the cover (be careful cutting!!!!). Hard clear plastic bends the light well! This works great!!! Can turn fans on/off and adjust the speed. Good steady range of power. Cheap and easy enough to access if this unit fails.Reliability: three of the four worked great out of the box (the fourth got handled roughly by me and didn't work). I used the other two to reaplace the fan switch on those white light/fan units that come with a pop-up camper (no pics, sorry). The red light in that case is just barely visible through the white plastic. Go ahead and buy some! I've had great luck with these controlling small fans!!!

Absolutely NO quality control. 😠 I ordered a pack of two PWM controllers. Neither worked. They would power up but no output. The issue on both was a cold solder joint resulting in no connection. If you have the skills required to track down the problem and fix it, this is a minor inconvenience. If you are a hobbyist that just wants to link modules, you will be very disappointed and need to return them.

I have always hated how our Motorhome / RV bathroom fan only had a wide open on speed, this was loud and annoying. Last year I installed a different brand but it was large, hard to install, and never worked quite right. But this one was so much smaller and fits under the crossbar as shown in the picture. I Installed this little gizmo in about 15 minutes and now our fan can be turned from barely moving to full speed. This has been working everyday as needed, for about a week. I will re-post if it fails prematurely.

I'm using this to provide a fan speed control on a small inline 12V DC bilge fan motor (2.5A max current). The off position gives a nice audible "click" and saved me having to add another switch.I haven't tried bypassing this to guage whether there's any power reduction at the "max width" setting. That would be disappointing, so might have to adjust review downward if that happens.Average Current usage definitely drops off as pulse width is narrowed, great for lowering overall power usage. My fan can run all day long on a 16aH battery.The controller doesn't seem to get warm, and construction/soldering looks decent. The thin capacitor next to the rotary control sticks up and is bent around easily, so be sure to mount this in an enclosure where parts and fingers won't contact.

These worked great at making the fans on my 24v 3d printer quieter but the wire terminals did not hold on very securely and the wires could be easily pulled out (hence the 3 stars). I removed the terminals and soldered the wires in the thru holes. At full throttle the fans were quieter, don't know if this from parasitic loss slowing the fans down or the controller cleaning up noise from the PS. Too lazy to multimeter or scope it out and i don't have a tach, I just wanted things quieter. I did not notice any audible line noise added to the fans but I have a slight hearing loss.Also used them to control the 24v Led strips I had on the printer and the on/off feature was a bonus. I don't need so much fine tuning here and will change this controller to one of those touch buttons.I would buy these again.

The product is good and does the job, but it’s too expensive.There are plenty of alternatives at a fraction of the price.

I use this device to control the current to a Nichrome wire foam cutter. It allows me to control the temperature of the Nichrome wire as it cuts though foam used to make RC airplane parts. I like the small size, ease of mounting and built in knob control. The power input and output connections are well labelled and easy to use. The price is low and two day Prime delivery make this an excellent value. I will order more of these for other projects.
