I bought a Playstation controller on eBay from a seller selling "refurbished" controllers. However, they are not refurbished at all, but are actually cheap fake controllers branded with the Sony trademark. I have one here with me from the purchase, and after opening it can confirm it is indeed completely fake. The quality of the product is horrible, yet branded with the "Sony" and "Dualshock 3" trademarks on the controller itself.
This is the listing on eBay: http://www.ebay.co.uk/itm/22178
