Be very Careful when buying Sony (Sony Interactive Entertainment Inc) DUALSHOCK Controllers. Sony is extremely happy to sell you their DUALSHOCK controllers but when you go to sell your DUALSHOCK controllers on platforms like Facebook, Sony spend a lot of money and time removing your posts under the trademark infringement. They will also decide to IGNORE any emails you send them to try and resolve this matter. Sony’s voice to their customers is they are happy to Sell their DUALSHOCK Controllers to you, but you are NEVER allowed to resell them (evidence in this link).
