With all the deep scratches on this product I can only imagine it was returned by someone else and then shipped to me, there were no instructions or literature with this product. NEW products just don't come out of the box scratched unless someone else uses them. The Allstar Performance comes in a box with a picture of the contents, specifically the air tank. It was repackaged and shipped in an unmarked box. When I buy NEW, I expect that from the start.
