I'm writing it from my heart. This is a question germane to IQ Plus that rarely comes up. I have concerns in respect to, the entire industry. They acted as if they had a chip on their shoulder. I've been itching to get away from IQ Plus for a long time. I'll take this into consideration. That's a good price. Obviously, what causes that IQ Plus so much different than the others? I suspect the only point missing from this awesome post is how you come up with IQ Plus.
