Query: Watch their videos on youtube. Same stuff for free.

These are great guys and certainly deserve credit, but I thought there would be a lot of detail in this video on their operation. It's the exact same stuff they put out on their youtube channel for free. In fact the content they have on youtube is more in depth. It's only 2 bucks to rent this video, but I certainly was expecting more.
