mostly, when your keyboard and mouse are plugged into an S1,
S1 will turn them into a controller to be compatible with game consoles.
with a C1+S1 bundle, the signals from your keyboard and mouse can be forwarded to a PC or a console directly and instantly.
it's called "Keyboard and Mouse passthrough" in our APP.
so you can switch between controller mode and "keyboard and mouse" mode whenever you want and without any delay.
but this C1 will not bring "smoothness" to you.
