I've been using this for about six months, since I bought it on Amazon on March 25th of this year. It was convenient to be able to charge it at the same time since I changed the Switch body to a wall mount, but I'm putting it up for sale because I'm not using it as much anymore. Including the main unit, it can charge six Joy-Cons simultaneously. There is no box or instruction manual. It will be wrapped in bubble wrap and shipped via post.
