SX Pro dongle is a neat idea but needlessly expensive, and it includes the cost of SX OS as well which means you can't just buy the dongle and skip buying SX OS itself.
This dongle allows support for Atmosphere, Reinx, and SX OS; all three of which you can keep on the dongle at the same time, as well as three other payloads of your own choice.

I've been using it for about 3 months now and no I am not being paid by them, just a suggestion.
