As others have said, it really depends on how much you like Marcelo's game. I will say that his instruction is not the best from a verbal standpoint, that is I feel there are a lot of details that he doesn't necessarily mention in the videos and the content is also very repetitious. I think the Mendes Bros have a teaching style that lends itself better to video than Marcelo does, for instance. But it is a great resource for his game, and if you're advanced enough to break down footage yourself the rolling is priceless. When I've used it I've mostly watched the 'in action' pieces of him doing, say, a guillotine hundreds of times in rolls and broken down what we has doing. That's really valuable IMO.
