I'm the same. I sold a few things on eBay a few months ago, nothing of great value, some old Nokia 8850's I had lying around and 2 Raspberry Pi's I had purchased but not used. I photographed everything, against a verifiable backdrop (in this the BBC website on my monitor) and filmed the product in use and put it up on Photobucket so that the upload was also time stamped. No problems whatsoever with the sales, but you know, just in case!
