Thank you for viewing! This item has been internally inspected, fully functional, and lightly cleaned on both the left and right sides. * Analog sticks have been replaced with new ones. * All buttons are working. * Charging is OK. * Remote operation from the main unit is OK. Furthermore, regarding the R and L buttons (which are directly attached to the internal electronic board and are the most difficult to repair when they fail), I have visually confirmed on the board that there is no immediate concern of detachment or peeling from the board, even when gently touched. We have spent time maintaining the item so that you can use it for a long time, but please understand that this is a used item. Please consider the photos for any minor scratches that may be difficult to see. The exterior has been lightly cleaned with alcohol and wiped down, but there may be areas that have been missed. We handle a large volume of items to offer them at affordable prices, so we appreciate your understanding. If you are looking for a perfect item, please refrain from bidding. We will do our best to address any operational issues that may arise, so please contact us. For the purpose of preventing product substitution, we will record the serial number before shipping.
