This blanket isn't worth the crazy price considering it caught fire and burned the first time you used it. I was welding a brace under my truck and my gas cap fell off and a piece of metal caught fire and I couldn't blow it up or cover it without completely suffocating it. I don't see any advantage over other materials of this thickness. Don't waste money. The reason it doesn't have a 1 star is because it's not fully burned out due to the thickness.
