Thank you for viewing. This item has been internally serviced, its operation confirmed on both the left and right sides, and has been lightly cleaned. Analog sticks replaced with new ones. All buttons function correctly. 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 if they fail), I have visually inspected the board and confirmed that there is no immediate risk of them wobbling or detaching. I have spent time servicing this item to ensure it can be used for as long as possible, but please understand that it is a used item. Please purchase with this in mind. There may be small scratches that are difficult to notice, so please check the photos. To prevent any swapping of items, the serial number will be recorded before shipping. Management number: m01
