Default DUC "almost constant speed" propellor

Anyone have any experience with the DUC ground-adjustable carbon fiber props? They claim almost constant speed performance over a wide speed range. They say they achieve this not through blade flexing, as has been tried before with some success, but "aerodynamically".
I recently saw some inflight test data that seems to back that up.
Not clear how they do it.
Has anyone had experience with it?
Craig, what do you say?

Check videos from Sting Flight on You Tube; also search the forum SportPilotTalk for the experience of one pilot with the Duc on his Sting Sport.
As I recall, he was favorably impressed.
