This controller is legal. I have pre-ordered and am very satisfied. Every button works and feels good. The controller is very light, so it looks cheap, but without a doubt it works. I would give it 5 stars but I doubt it due to the fact that ALL Switch controllers including joysticks are known to ghost from analog sticks and my wired PowerA controller is showing signs of ghosting. I hope this controller has updated sticks, but we'll see. If there's no ghosting, then this WAAAAA controller is better than Nintendo's Pro Controller. UPDATE: I've played a lot with this controller and so far it's holding up. There are no halos on the joysticks and no signs of wear on the buttons. Definitely worth your money! **UPDATE** MAY 2019 My controller just died after 7 months of use. I haven't even worked a full year. I just turned it off and never turned it back on, even with a fresh set of batteries. CM.
