I left after a month... it really wasn't for me. I really liked Braulio's DVD sets that were what I'd called advanced fundamentals, but this stuff seemed REALLY not geared towards my game at all - lots of guards and unorthodox moves that felt completely foreign and unrealistic for me. Lots of stuff that relied upon your opponent being unfamiliar with what you are trying. Might just be because at the time it was new and trying to differentiate, might also be good for the higher level guys looking to expand their game.
I'd certainly not go with it over Marcelo's site.
