Query: Great Product!!

I bought this Yoga Kit for my girlfriend, so I can't really give a first-hand review. However, she has used it nearly every day since I gave it to her, and she is really enjoying it. The matt and ball are constructed very well from quality material, and have withstood all punishment that she (and her 9 year old son) have inflicted upon it. The workout video seems to be of perfect length and skill level for the intermediate Yoga enthusiast. This product would have earned 5 stars if the workout video came on DVD rather than VHS, but that's the only downside that I can think of.
