This product performs exactly as I hoped it would. I would have preferred it to be on a neat roll and boxed for ease of use. Instead it came in a plastic bag and looked like it had been stuffed into a pocket. My only other comment is that the hair dryer doesn't shrink. I had to use my propane lamp, which didn't bother me, but others who might only have a hair dryer might find it difficult to work with. A conventional heat gun works best. But I like hoses.
