FANTASTIC ITEM! Great price! Works perfectly as described. I needed something to make a 3V DC motor run at a slower speed. Unfortunately I’m not well versed in electronics. I was going to ask someone on FB what to do. Then I thought of asking google AI what to use. It came up with this very controller. No instructions but super easy to install. The four terminals are clearly marked: Motor plus and minus, and Power source plus and minus. Your wires are screwed in with tiny screws and held firmly. Can’t be any easier! It’s small and doesn’t take up much room, and the control knob clicks when put turned off and on. There’s a pilot light showing when it’s on. Two for $7 with free Prime shipping! You can’t beat this!

The speed control doesn't consistently work between the 2 I was given. The knob didn't fit tight and falls off.

One worked good the other didn't work at all

This compact PWM controller handles its full 1.8–12‑volt range cleanly, giving smooth, predictable speed control to a 12‑volt fan without any stutter or dead spots. Installation is simple thanks to the clear terminals and small footprint, and the board feels sturdier than most budget options with solid solder joints and a responsive dial. Functionally it does exactly what you want — stable output, wide adjustment range, and no noticeable heat buildup — making it useful for fan tuning, small motors, or battery‑powered projects where efficiency matters. A dependable little unit that performs well for the price.
