Review: Works great - For Roy that left the 1 star review, you have the bracket on upside down and backwards. It's not meant to be mounted that way. Try watching a video if you can't figure out how it's supposed to be put together. I installed this today at my camp as a setup for the new fridge. I did have some small leaks at the spots at the end of the the braided lines but these went away after a few minutes. It would be nice if it came with some documentation, but it's pretty straight forward.
Review: No Instructions - EDIT: NOW INCLUDED BELOW - The seller QUICKLY provided the attached images, which satisfy the need for instructions and answers my questions! The hardware looks good. I see there are reviews with issues, and if I experience those then I will amend this later (I'm pretty good at coming back to reviews, believe it or not) but if you don't hear back then assume I'm please enough to keep the new five-star rating. ORIGINAL two-star review: Everything looks new, but there are no instructions. Those were probably left out when it was returned. I suppose technically it is new, but it was definitely a return. Honestly, it looks straight forward to set up. I just want to know what the dial settings are, and how the automatic cutover works. Does the dial only use one tank when it is selected and not automatically move? Does the dial move to the full or empty tank? At what pressure does it do that? All these questions would have been nice to have answers.

## Features

### ⭐ Don't buy it unless you feel like dumping propane into the atmosphere
*by A***R on December 25, 2025*

Go find it somewhere else I made the mistake of buying two of these I have a slow leak on one side now and the first one blew out completely and drained a 30 lb tank while I was away I have one side cut off now and I am currently exploring another way to go about this but I have bought two of these things and both of them were bad
