Bests & Worsts Reviews from Amazon

I ordered this heater to use in my total electric 21 foot hard top camper to save on the batteries. It does and will heat that space. When the temperature drops below 30, its not quite big enough though. The only thing i don't like about it is, it does not have a control knob to turn it up and down. When it's on, it's on. It will also use a disposable propane tank in about 4 to 5 hours. I used it with a 20# bottle and it will use that in about 3 nights.
