For what it is, and the video set is very specific in its intent, the 3 DVD set is spot on. It manages that careful balance of giving a methodology while being flexible; correcting flaws while maintaining a method to get the desired results. The videos not only show why things must be done within the framework, but how to set up a framework to accomplish the specific tasks needed to establish a solid foundation and common problems and their solutions.
The first disc on stance alone is worth the purchase price. The 3 disc set isn't cheap, but a lot of that is simply because it is 3 discs. If the price were divided amongst each disc, then it would seem in line with other offerings, and cheaper than many. That said, the length is both generous and the information abundant. This isn't a pool DVD where a player shoots a bunch of shots and just happens to sprinkle in a few tidbits. The videos are concise and focused.
I have a few qualms. The production quality isn't the highest you'll see. It's not bad, but fairly average for today's video offerings. The camera is static and often times the angles aren't exactly what I'd like to see, but the same idea is shown from multiple angles enough of the time that this isn't a really big issue.
I really can't recommend this product enough for the player that is looking at developing and correctly the fundamentals. As important as those are, it is a video set that every player would benefit from, however, if you are a player who is already happy with the fundamentals and looking for advanced position play, pattern play, etcetera, then this isn't the series for you. The DVD set does what it does very well.
