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. There is some color fading on the rail surface. There may be some scratches that I have overlooked, so please check the images as it may be difficult to see. 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 reconfigure the controller update, stick calibration, etc. from your Switch console. 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 thank you for your understanding. Immediate purchase ⭕️ Feel free to comment if you have any questions. Regarding price reductions, please use the price reduction request function.
