Review on 🔆 Versatile Silver 12 Volt DC Dimmer for LED, Halogen, Incandescent Lights - Ideal for RVs, Autos, Trucks, Boats, and Strip Lighting by Aaron Guy

I liked the look of it. For such a simple component, 30 seemed expensive, but I wanted aesthetics. bought two of them. I decided to test this before permanently plugging it into my camper build but it doesn't work. I tried connecting them two different ways as recommended, in one line but with ground. neither method works. It's absurd that I got a useless cheap $30 product. don't risk buying this, just get a cheaper dimmer that's more likely to work.
