Great light weight easy dimmer with off position. No click on off but off - on function. Kinda pricey but PMA approved and works with all type bulbs. Led, no problem. I would buy again if certs needed.

Functions very well stays cool even controlling ten post lights. Any position between full off and full on splatters the square wave signal into my headphones. It is quite loud. Any thoughts about fixing that? Some sort of lowpass filter? Thanks.

Product works but is stupid expensive. Should have a positive “click” off, but doesn’t. Cheap looking knob too

I gave it 3 stars because of the very short threads. It works great as a dimmer, but what should be a straight forward installation will now require some modifications to the panel.

Had to modify dash and switch to get the stem long enough to start the nut

The dimmer is great but the label.... Why do you people send a piece of cardboard that looks like a sticker but it is just a piece of cardboard? I have seen so many people glue these cardboard squares to the panel, and after about a month they look like total garbage because the edges are peeling and curling. Make it a sticker. You make the template a sticker, but the actual label is not? This makes no sense.
