I don't see anywhere on that site where the marketers of this device have measured any reduction in drag or lift, only streamer videos which don't tell us anything (lay the tailgate flat and the streamers will point backward, but that's a higher drag configuration than tailgate up).

ETA: Under FAQ they claim 5-10% improvement in fuel economy. Snake oil.
