Operation confirmed. The sticks have been replaced with compatible parts. Other than the above, no parts have been replaced, but the previous user may have replaced parts with compatible ones. ----------------------------------------------- [Confirmation Details] Simple operation check on the home screen. Response of various buttons Player lamp lighting up Stick center position in stick calibration Battery life is unknown. No other operation checks have been performed. ----------------------------------------------- This is just a layman's check and is a used item. No returns or refunds. I have not performed long hours of operation, so I have not been able to confirm the battery life, etc. There is a possibility of slight differences in button response. It will be wrapped in a bag and bubble wrap, and shipped via Yu-Packet Post Mini. Thank you.
