I've purchased a fake memory card off Ebay along with many others from Ebay member sonyproduo. It was very slow, the data became corrupt and it was switching my PSP off. When returning it I was not given a refund. I am trying to get Ebay to stop sonyproduo from selling any more fake cards but Ebay are doing nothing. I am also trying to get paypal to stop taking payments but they are doing nothing. Sony have been contacted by another member and all as they told them was to contact the police. So Sony aren't that bothered. So buyers beware.
