Joy-Cons that have been confirmed to be working after maintenance. The sticks have been replaced with new 【4th generation】 ones. There are no button issues. There are no problems when attaching and detaching them from the main unit. Latest update installed! Can also be used with Switch 2 if connected wirelessly. They are in excellent condition, close to new, with no signs of use or scratches. There may be some minor scratches that I have overlooked, so please check the images. Please refrain from purchasing if you are looking for a perfect product, as this is a used item. I will check again for any defects before shipping. When disassembled, I will do a simple cleaning and wipe the surface with a disinfectant sheet and polish it with a melamine sponge, removing invisible fingerprints, etc. When the product arrives, please reset the controller update, stick calibration, etc., from your Switch main unit. In the unlikely event of any defects, please contact me before you rate the product. I will not be able to respond after the rating, so please understand. Immediate purchase is OK. Feel free to comment if you have any questions. For price reductions, please use the price reduction request function.
