All my friends are buying cheaper versions online and NONE of them work. My honest theory is the white colored tip the inside of the usb has. All of their adapters were with a blue tip. I think (I'm not sure) that it identifies if a wire is usb 2.0 or 3.0. The switch would only work with a USB 2.0, which is the white tip. Anyways worked like a charm. No lag on Fortnite, Rocket league, Mario Tennis/Kart, and Paladins.
