This is an NBCP Pro Controller for the Switch. It basically has the same functions as the official controller, with the addition of back buttons and a turbo button. The back buttons are built-in paddles that are easy to press and don't get in the way. It has similar specifications to PDP products and is easy to operate. I connected it wirelessly to the Switch and used it once, and it worked without any problems. I only used it for about 30 minutes, so it's in good condition. The purchase price was 4999 yen.
