Scholars in Collars?

Anyone ever tried this training school?

No but I have heard great things about them. I used Don't Blame em Train em and I felt it was OK but I mainly learned 10 ways to get your dog to come back or stay and nothing more. I was informed that i would need the advanced class to learn how to get my dog to drop a toy??? The owner is very arrogant and talks down to you. I felt like I was in boot camp.
