This is a defective Nintendo Switch (original model) with malfunctioning Joy-Cons. Please note that there is also some dirt. Blue Left: The stick's up and down directions are unresponsive, and sometimes it inputs up automatically. Attaching it is difficult. Red Right: A, X, and R buttons are unresponsive. Attaching it is difficult. Black Left: SR button doesn't work. Light doesn't turn on. Black Right: R button doesn't work. SR and SL buttons don't work. Light doesn't turn on. The right Joy-Con is often detected as detached, but the Switch used for testing is 8 years old, so it may be a problem with the console itself. All Joy-Cons can be powered on and charged. They cannot be used as is, so please use them for parts or repair.
