Rating : - OK, not great
We purchased the heater while camping at high altitude in a pop-top camper when the temperature started reaching near-freezing a night. It is compact, easy to light and small enough to fit into small tents and/or spaces. But it was not adequate for the space in the Coleman camper.
It did take the edge off the cold, perhaps warming the interior 5 degrees or so, but never made the camper warm. We still required warm clothing and even a blanket around our knees/laps if we wanted to be able to sit up and read or talk.
It would probably work better for a small tent, but it simply does not put out much heat. You can warm your hands over it, if you are careful.
Next time I would purchase something with a higher BTU output.
