I've had this about a week now, and have used it every day. I like it, but I don't at the same time. I like it because it heats metal for me to shape. I don't like it because I can't just use one burner at a time if I'm doing a small task. The flame backs up into the other burner and melted all the paint off. And I don't like that there isn't some sort of door on the back side. So much energy is lost just venting out the back. I've gone though nearly 30 gallons of propane already. My one burner will make a 25 gallon last nearly a month. If I am doing a long piece, fine. But most of my projects fit in the box as is. Please make a door. I don't regret buying it. But I won't buy another one unless they make changes.
