Wireless controller, compatible with Nintendo Switch. Purchased last November. I threw away the receipt and box, but shortly after buying it, I noticed that the A button sometimes doesn't work. I threw away the receipt before I could return it, and I haven't used it since I noticed the issue. It might work properly if repaired, but it's a hassle, so I'm putting it up for sale.
