T-Splines For Rhino?

Anyone here useing T-splines for rhino? I watched the demo vid and plan on trying it out, just wondering if it’s worth the time, seems pretty smooth though. likes? dislikes?

I have tried it very briefly. It seems like a useful tool if you are using it in conjunction with a polygon modeler. It’s worth trying it out to see if it works for you and what you want to achieve.

yeah… it seems like it creates complex surfaces with good continuity quickly. Patching together Nurbs surfaces is time consuming when I’m looking for a result that has good continuity, (zebra-stripes cleanly).
I think this may be a time saving tool, just want to see if anyone has had good luck with it.
