New roofing product called "FastFelt"?

Hey,
Anybody know anything about this new roofing underlay called "FastFelt"
I’ve heard about?
Any help please.

fastfelt.com/

seems like it might be good for high wind or steep roof applications…might be faster to apply too. Anyone have any experience with this?

dhindublin, thanks for the link.
