8 Bitdo have Updated their controllers to work with the Switch
This is great news for those wanting to purchase a cheap controller but weren't able to. Well, now they can. The only problem is that the 8 Bitdo controllers are meant for NES/SNES games so not adequate to play games which require too many buttons (would work fine with Mario Kart 8 Deluxe, for example).
