My son is enjoying this controller with his switch. When he wanted a new controller because he was having trouble with the joycons and was thinking of just getting the nintendo pro, I remembered JDM had posted about these controllers. So I was - oh oh I know a good controller.
He is using it right now and I earned a few Dad points.
Been using mine tethered (I’m a dinosaur) to play Steam in Big Picture mode. Works swimmingly for me. I’m getting ready to test it on a RetroPie soonish
