I purchased this unit new directly from Outlaw Audio. I can email the buyer the original receipt if requested. It was only plugged into a Transparent Audio surge protector which also cleaned any dirty electricity.
The unit came with a minor curve in the metal in the back. The unit always worked fine and its in the back so I never saw it. It was brand new and not refurbished, so the imperfection never bothered me but like to be up front about the condition of what I sell.
