I felt that the official Joy-Cons were expensive, so I bought these on Amazon 4 years ago. They are compatible, but they have gyro and vibration functions, and (although it may vary from person to person) you can play Splatoon just like with the official Joy-Cons. Each has a USB-C charging port. The middle part can also be used with official Joy-Cons. They were working fine until recently, but the left stick no longer registers down-left input. The red controller has no particular problems. The appearance is quite clean, so I've listed them as "no noticeable scratches or dirt," but there is a part that doesn't work properly, so they are considered junk. They are already discontinued on Amazon. Please consider these if you are knowledgeable about repairs, or if you like knock-offs or disassembling things. I will dispose of them if they don't sell by the end of October.
