Worked great for a few days but then something came loose in the burner and turned the swirl jet style flame into a soft lighter style flame. It still works if you shake the burner head a bit to get the parts in place, but after paying around $100 for it, I expect more. RMA'ing is how I type. I would advise anyone considering a purchase to only use propane as it appears that the heat from the Mapp-Pro gas we used was enough to expand the burner head to the point where the parts in the inside were no longer in place. It turned a lot of heads and quickly heated up whatever it was aimed at, but I expect more than a few days use from anything that costs me $100.
