Not for large shelters. Inexpensive @ $44
January 10, 2018
I have a 3 person uninsulated ice fishing hub which is 80" high with 34 sqf fishing area. It was a cold (-20C) and a windy day and the heater kept me from freezing inside the hub on the low setting. I can't honestly say that it was warm inside, it was just not freezing cold so i was able to take my survival jacket off. On the high setting it would have probably provided me a bit more heat. But my advice is to get a higher BTU unit if you like your quarters warm and cozy, especially if you have a large uninsulated tent. This heater is probably good enough for a 1 person shelter with it's 2890 BTU rating. I am only reducing 1 star from my rating simply because Amazon did not provide a BTU rating in the description (manufacturer website does, but if we're shopping Amazon we shouldn't have to refer to the manufacturer website), otherwise the unit performs as expected.
