Genuine Joy-Cons, confirmed to be working after maintenance. The sticks have been replaced with new 【4th generation】 ones. No button issues. Attaching and detaching from the main unit is also problem-free. Updated to the latest version! Can also be used with Switch 2 via wireless connection. There is some slight wear and tear. There may be some scratches, etc., that I have overlooked, so please check the images for confirmation. 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 handprints, 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. Please use the price reduction request function for price reductions.
