Just bought this off ebay, it claims to work with ps3. If they're lying about it not working with a ps3 and false advertising it will be sent back. But I'm not expecting any problems since they said it works with a ps3. This company has nothing but great reviews with 99.9 percent rating on ebay and they have an official website too.
