Ok so I watched all of them.
Overall I agree with justthetip. This is an amazing set. A lot of the stuff I've seen elsewhere so it's not 100% groundbreaking technique. What is groundbreaking is the systematic way in which he teaches you the "why" and "when this instead of that" and the details. Danaher is a great explainer of both moves and concepts. To me, he's on par with Rafa, Gui, Caio, and Braulio and better than Ryan Hall. Where I think he's even better is how he takes thirty moves, all explained well (which others do) and turns it into a system, all explained well.
ONe thing that hasn't been mentioned is the back takes section. I've seen all of these techniques from either AOJ or seminars with BB who are on bjjheros. So they're not new techniques, but I think this set teaches them better. They're not just a collection of turtle attacks, there is a hierarchy of which one you want to attack first. The details of the angle of the one where you pull to the side have been eluding me until now, and I've been watching Gui and went to seminar where Mario Sperry taught it.
I was finally able to try ~5 tips/techniques in rolling today with a blue belt and it worked right away, without even drilling. It's not like fifty step moves or something that needs physical attributes.
The one caveat is the one everybody else has already said. Danaher is pompous and obnoxious. He repeats himself over and over (this is sometimes good but not always). The second dvd is a waste, the first is about 40 minutes too long.
With that said, we have the ability to play the videos at increased speed. 1.5x is ok on mobile, on computer you can get away with 2.5x with the increased quality of video. This trick helps decrease the bad of Danaher while keeping the good.
There was a promotion "digitalchapters" that gave 30% off. Great deal at that price.
I'll probably get his other set now and the headlock one when it comes out. I wasn't convinced before about the hype but I am now.
