I had a brand new Ebay Account and this was my first sale, the same day he received the item, he stated that didn´t work and wanted his money back, i send them links on how to install the spare part for the controllers, but in munutes he said that he tried and didn´t work, that he could accept 50% discount. i agree, since a negative would kill my new account. So he basically make an extortion to get a half price item without saying any word who incriminate him, just an opportunistic person who need to be watch for for his schemes.
