The following is a copy and paste from the product page of an item I purchased. I mistakenly bought this thinking it would work with the Nintendo Switch, but I realized it's not compatible. I have no use for it, so I'm putting it up for sale. It has been opened but is unused, and I will send it to you in almost the same condition as it arrived to me.
