I use this DVD all the time. I like the sequencing, that each practice is under 60 min and that he holds a lot of the poses for a long time. It's also filmed beautifully.
I'm not a big fan of his personality, though. I think his tone is too aggressive ("Now soften your face and breathe!" he yells). Also, the participants are EXTREMELY flexible and can be intimidating at first if you compare yourself to them. I don't know how much yoga experience you have, but if you don't have much or aren't very flexible, be careful not to try to go as deep into the poses as they do or you can really injure yourself.
I wish the DVD were chaptered better, but for $13.00 for 3 workouts, I really shouldn't complain.
