I've only used Jason's free pattern recognition videos but they are really good. He is very clear and in the main the patterns are well known and have stood the test of time (e.g. the Gartley Pattern).
It is true that these patterns will struggle in a strongly trending market but that only happens a small amount of the time. In a range bound market or when the trend isn't that strong they work very well. I'd argue that because you are trading retracements of strong impulse moves the trades aren't really counter trend as some have stated in their reviews.
This works but you have to apply it consistently and this is where most people (including myself in the past) fail. You will get losing streaks but the winning streaks should be larger and that is pretty much the game.
