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. Multiple scratches and plastic whitening are visible on the sides. There may be oversights such as scratches, so please check the images as it's difficult to convey everything. 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 perform 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 reconfigure the controller update, stick calibration, etc., from your Switch console. In the unlikely event of any defects, please contact me before giving a review. I will not be able to respond after the review is given, so please understand. Instant purchase is OK. Feel free to comment if you have any questions. Please use the price reduction request function for price negotiations.
