Does Reasnow work good on Nintendo Switch?

[Triforce]

Hi!
Just heard about this product and I currently own a Nintendo Switch.

I wonder if this programs works well on a Nintendo Switch and if it emulates an Controller input? (As a few games I know of on other consoles such as PS4 disable certain advantages when you use K&M instead of a controller).

And If I upgrade to the Switch firmware, Can I downgrade to PS4 firmware again?

I don't seem to be able to edit my post.

Do I need to purchase a Pro Controller or something to Plug into the dock?
Or do I only need to plug in a K&M to the dock, Then that to the Switch?

Or do I need to plug in, Pro Controller, K&M?

Thanks!

Should I exchange this PS4 controller to something like a Switch Pro controller or can I leave it empty?

1. no need of Pro controller for SWITCH
2. just prepare your usb keyboard and mouse(5000 dpi or above is recommended)
3. cross hair can now support all consoles with one firmware, no need to change firmware for different consoles.
