I almost never return items but I will return this one. The nice metal heatsink above? Yes, it's a thin piece of molded plastic that looks like steel or aluminum. After a few minutes of operation, the hose will become hot enough to burn you. I smelled melting plastic and after a few minutes there was some smoke. There's no way it could ever reach 150psi (or even half that) without igniting. And I certainly wouldn't let it run for 30 minutes. Don't waste your money on this junk.
