My water heater died and is costly to replace, tired of taking cold showers so I looked into portable water heaters, wanted on with small propane tank and rechargeable battery. Coleman unit fit the bill. I read the mixed reviews, watched the youtube videos and purchased. The only negative thing I can say it that it did not come with and ac adapter to charge/run at home. I was able to source one but I also found that the Coleman Powerchill ac adapter works as well, just a 120V to 12V cigarette type adapter for home. Used 4 times out of the box since I had no way to charge it without driving around for several hours. It will deliver scalding water so be careful. There is a trick to get it started just like a regular gas water heater, you have to hold the button down in the pilot position for a few seconds after it ignites to allow the element to get hot enough to keep the pilot from going out. I use a 14 gallon storage container for water, the 5 gallon jug that came with the unit was a bit light for my shower time. Shower hose is a little short but usable, Can't speak to longevity but I am happy to have hot water again. I do use indoors with exhaust fan on and a CO2 detector nearby, obviously despite warnings that is outdoor use only. Bottom line it works, wish I had one when I was a boy scout and camping
