JOY-CON Left (L) Thank you for viewing. This item has been tested, lightly cleaned, and serviced. The analog stick has been replaced with a new one just in case, so I think you can still use it for a long time. Furthermore, regarding the L button (which is directly connected to the internal electronic circuit board and is the most difficult to repair when it malfunctions), I have confirmed during disassembly and cleaning that the solder joints are not coming loose, that it is not wobbly, and that there is no immediate concern of detachment or peeling from the board. I have spent time servicing it so that you can use it for as long as possible, but please understand that it is a used item before purchasing. Please check the photos as there may be small scratches that are difficult to notice. All buttons work OK Recognized OK when attached to the SWITCH main unit Charging OK Communication operation OK when detached from the main unit The exterior has been lightly cleaned with alcohol and wiped, but there may be some areas that were missed. We are handling a large volume to offer it at an affordable price, so we would appreciate your understanding. Please refrain from bidding if you are looking for a perfect item. In the unlikely event of operational problems, we will do our best to assist you, so please contact us.
