I purchased his course about 6 months ago. Being completely new to trading, I took my time studying the information. I started paper trading after about 2-3 months with decent success. I then switched to real money and had moderate success. This is mostly due to me trading on emotion and not being able to detach myself.
However, since Harvey released his updated course and new detailed videos, I have had more consistent success. As of today, I have traded 11 days since reviewing the new material. Of those 11, 8 of them are winning days. My biggest losing day was $0.10/share. I actually think I would have come out positively that day but I was paged by my work and had to deal with a customer issue (I'm on the west coast and trade in the morning before I go to work). By the time I was done dealing with the customer issue, it was about 8am PST and I had missed the setups I was watching (my first one was a losing one, obviously).
I have 100% faith in Harvery's system. Don't get me wrong, I don't want people to be over optimistic. This system is not as easy as Harvey makes it look, especially for someone like me who is still new to the market. Keep in mind that Harvey has been trading this system for many years and makes it look easy (just like professional athletes make their job look easy). Most people aren't going to be able to trade 1000 size lots of 4-5 different shares at the same time. I personally rarely trade more than 1 at a time, but I'm still learning, so I'm more comfortable this way.
I also want to point out that in those 11 days, I have made more than double the cost of his course. I am still playing pretty conservative (100 shares at a time).
I've also read some people being skeptical of the price....are you kidding? If you can afford $149, maybe trading isn't the right thing for you.
