My wife and I have used this heater over a two year period in our Vanagon Westfalia.
The heater is troublesome in that it goes out frequently, sometimes because of the slightest movement of air. At other times it seems to go out because the propane cannister is nearly, but not entirely, depleted. At still other times the heater goes out for no discoverable reason.
These symptoms occur whether we use the heater with disposable cannisters or with a 1 gallon refillable tank. (We use a filter with the refillable tank, but that has not helped.)
We avoid the use of disposable cannisters because they are much more expensive to use than a refillable tank ($4 for 1 pound vs. about $3.50 for about 5 pounds) and because we don't consider the disposable cannisters to be environmentally friendly. Disposable cannisters are also difficult to dispose of properly.
Perhaps our heater is defective?
All this said, we consider the heater safe to use and, importantly to us, it is very quiet. It produces enough heat for us with the pop top raised when the ambient outdoor temperature is 32 degrees.

I've had one for 3 years and use it to heat the car compartment of our race car trailer. It works wonderfuly, never goes out unexpectidly and works as well with the disposable tanks as it does with large ones. I do have the hose for the large LP tanks. If you need portable heat in a compact package, get one.

Don't buy it! It's DANGEROUS!!!! I bought one of these heaters and just the second time I used it, it caught on fire after it was running for about 3 minutes. There was a recall on two other models of this heater but not for this one. I was lucky I was right there and able to shut off the fuel before the fire got out of control. After turning off the valve I was able to blow out the remaining flames. There is a very lousy looking bit of plumbing that goes to the regulator valve. The connector was leaking where the tubing goes into the regulator from the burner. The fuel was leaking around the threads. I took the heater apart so I could access the faulty area and discovered some sort of granular powder fell out from the threads. I think they must have used some sort of cheap thread compund when the connected these parts together. The fire left nice black marks that allowed me to quickly locate the exact location of the leak. When it was on fire, I couldn't see it because it is obscured by the fuel tank and the plastic housing of the heater. I took it apart and cleaned the rest of the gunk from the threads and then applied teflon tape instead. The unit no longer leaks but I don't trust it at all. I wish Mr Heater would issue a recall and pay me back for it so I could use the money to go buy some other product. I'm afraid to sell it to someone else unless I explain to them the danger and they understand the risk involved. It does seem to work great now, too bad I had such a bad experience. I just hope nobody else has a bad fire or gets killed using one of these. If you want photos, I have some showing the location of the leak and what I did to repair it.
