Genuine Nintendo Switch Pro Controller. Functionality has been confirmed. All buttons respond correctly, and there is no stick drift. The length of use is unknown, so the battery's degradation is also unknown. The surface has been wiped and disinfected with alcohol. Please check the condition in the photos. There are no major scratches, but there are some minor scuffs. If there are any issues with the functionality, I will accept returns, so please contact me before leaving a review. #Nintendo #Switch #ProCon
