I have bought this flyaway tool from a seller on ebay that claims it is a new genuine product, however there are telltale signs such as the magnet not being strong, there being imperfections on the item itself and the plastic around the connecter being a shiny plastic instead of matt. I have compared this to my other attachments. Please could someone help identify if it is a counterfeit? The seller is offended and point blank refuses that it is a fake.
