Literally stole about $800 from us when we purchased 2 sessions and wernt thrilled with the 1st one. We wanted to be refunded for the cost of the 2nd session (we had to pay upfront) but they refused! I went through hell with them emailing back and forth!
In the end we had made some progress with the shock collars and our dogs were walking nicely but there was NO progress with the agression AT ALL!! In fact Im not sure they know how to handle real agression! Spend your money on a CD set, dont waste your time, sanity and money here for real dog issues.
