Also the product reviews here are not legal (they refer to the mouse pad and keyboard). Controllers cause the original switch controls to disconnect from the system. Oh, and you still need the original Switch controller to turn it on. Well if you only play single player games I think you're ok, but if you mean some 2 player games forget it. After all, you can't even tell who did it. Pooh. I only had to send it back a few hours later.
