I have a bunch of used third party controllers 5-6 (Wii U, Gamecube, Wii). The Wii U ones are average at best. If anyone is interested they can pick up for free or pay for shipping at actuals and have them.
Accessories - pro controller, case, screen guard , grip....a good Nintendo licensed grip is must for handheld.
That link isn't opening up, maybe it's country specific. Look for Switch version HAC - 001 (001)
