OK, I just went back and watched the video. I can see how this saddle might feel better when you first get on it. However, the saddle itself flexes like crazy with the rider in place which would make it prone to breakdown very quickly. And, there is a projection that will be pushing into the perineum area, not a good idea ever if it's flexy and bendy. And, the amount of movement in the saddle would potentially cause problems with rider stability, bike handling and low back irritation.

I would still be interested to try one just to see if my guesses on how it would behave are correct. Who knows I could be totally wrong and this could be the next great thing. But I doubt it.
