MY trainer met him and he pretty much said her horse was flat out dumb. When he is the most talented four-year old I know. So as far as him personally, I don't like him. He was very rude.
As far as his teachings, they can be really helpful. I just don't think that you need all the fancy tools he says you do... Horses don't know any different! Lol.
But don't ever stop posting your opinions, especially if it is something that has worked for you!!!
