A solid rheostat especially for the price.
I bought this with a 6 pack of 6 LED puck lights to install in my Cargo conversion trailer to operate on an off grid or plugged in and inverted scenario. I bought a second 6 pack of puck lights so my rheostat currently operates 12 lights and it works well. The rheostat seems to be of decent quality and works well with the lights. The switch has a positive on/off detent and a smooth rotary action through out. The one thing I don't like is the the switch housing can rotate inside the switch plate once installed if the friction nut becomes loose. Not a deal breaker but something to think about when installing. The jam nut needs to remain tight. So far very, very low level of flickering and only briefly while adjusting. I would buy again. Price point out allows 5 stars.

Perfect in my RV application
Worked perfectly in my application. I used it to dim an LED light strip that was too bright in my RV. Now we can turn it down to an extremely low level or crank it up to full brightness. The only comment I have is that in my application, I first wired it backwards, which is very easy to do. The dimmer only dims if you install it the right way.

Defective
Banged my head on the wall for a long time why no matter what wiring configuration I did, the lights just stayed turned on. Tested with a multimeter, continuity is never broken with the dimmer. Entirely defective. Junk

Almost perfect. Probably the best you'll find on the market....
Nearly perfect. I bought these to control the dimming on some Low Voltage LED puck lights in a Bambi Trailer. It does work. Nearly perfect. But it could be smoother. A lot happens at the first bit of the dimming curve and then they go out with lots of room left on the knob.

Small and easy to install
Much smaller than i had imagined, bought one to compare to some other dimmer switches that matched my existing switches, i really like these, its a great addition to a dimmable 12v system without needing too much space.

Does an awesome job- full dimming AND POWER SAVINGS
Ok. It works like it should first off. I have this wires with 8 Acegoo puck lights. When turned down to a nice evening level, 0.06A. That is just crazy good. I think they got the PWM right! Love it. One note: I removed the mounting plate to install in my system. The threaded shaft of the switch is short and it wouldn't work on a 1/4" thick wall. I was a little surprised but worked around this in my application.

Great Dimmer for my RV
I bought this dimmer to use in a new travel trailer. The dinette has 4 LED puck style lights in the ceiling over it which are too bright at times. The wiring instructions are helpful and installation should be simple if you understand 12v wiring and making proper connections. In my case the original on/off switch had only positive wires connected to it so I had connect a negative wire to the nearest light (all the lights have both positive and negative wires) and pull it back to the dimmer switch. This is a good quality dimmer that works smoothly with no flickering. Really happy with it! Supper with nice low lighting is way more enjoyable.

Great dimmer!
We have two dimmers like this in our camper van that we use with our LED puck lights (same brand). Works great, dimmer works well. I've had other brands in the past that caused the lights to flicker on lower setting, but this one doesn't do this. Works great. Love that it is small and not too apparent in the camper.
