I LOVE the fact that this is so much less expensive than the Nintendo branded charger, and it also has cool indicator lights to let you know when everything is charged I also used this with pro controllers. I like that it provides me a place to keep my pro controller and it takes up less space then when the controller is laying on the table. It is a bit hard to find the plug on the pro controller since you need to plug it in upside down, and taking it out is difficult because it is securely plugged in and you need to brace your hand on the tops of the light up towers in order to have enough leverage to unplug the controller. That being said, this is totally doable, but might need some explaining if you have a friend over who just picks up the controller and the rest of the charging stations comes up with it. Don't wiggle it, just brace your hands and pull straight up or you risk damaging the charging station and controller.
My boyfriend liked this setup so much that he bought one too! I would recommend it if you have more then one pair of joycons!...
