Best gift I ever bought!

Gave it as a gift to my son so he could sit outside and have a cigar with me over the cold winter months. He lives in VA. He raves about it every time we video chat. Absolutely loves it. Actually says it's too hot. Got a great deal on a black friday deal! Best gift I ever got him.

Great Burner

I bought this to heat up the garage whilst I worked on my truck. It heats up the space very well. I've never used a dual burner style propane burner set, so I can't really compare. I just seen that this offered a higher btu count.

Awesome heater!

Heats a 2 .5 car garage with no problem in low settings, not sure about temp but I was about to sweat… used for about 9 hrs and used about 1/2 of a 20lbs tank…
