I ordered the 14 DVDs. It arrived in two days. I haven't yet gotten through all of them but gave them a one over to check them out and now am going back slowly, having gotten through a couple in depth. So, with the caveat that I still have 12 DVDs to watch all the way through I thought I'd note I'm happy with the set. The quality is clear, although it is not slick or super professional in terms of the video production. But, what is important to me is that the exercises and techniques are clearly explained by a narrator in clear English and the demonstrations are easy to follow. I am glad I got the entire 14 DVD set because I feel like it really is a whole program and that I've already benefitted from it. So, I recommend it.
