Review on ⚡ Enhance Motor Speed Control with ALEDECO Voltage Motor Speed Controller by Dustin Keller

I bought this for an unusual purpose, I was building a heat exchanger for a fireplace and needed to fit a small fan in a 2.25" piece of black iron pipe. I connected this controller to a small drone motor and a 2 AA battery box. It was very easy to connect and works well, it even has a small LED to show it's on. Adjustments are smooth, not graduated. I wired it up in about 2 minutes, just connect plus and minus to the power supply, do the same with the element that is powered and tighten the set screws to hold the wires in place and voila! done. Hard to believe it was only $5. I'll probably buy a few more to have on hand, this seems like an incredibly useful little gadget at a very reasonable price.
