Very impressed with this product. First the construction of each component is very solid. The packaging for shipment was very solid. Very little chance of damage during shipment. The instructions and video are clear and easy to follow. My personal experience as I begin to train my dog has been outstanding. After only a session or two my Dalmatian is understanding what to do when she hears the beep from the collar. I am insuring that this step is solid before I hook up the leash. As many people are aware Dalmatians are a stubborn breed but this product gets past that. I am confident that I will not have to resort to the static shock at any point. It is there if needed however. Finally I want to congratulate the folks behind Loyal Leash. They are there if needed. Their customer commitment and support is beyond outstanding. I highly recommend Loyal Leash and the folks behind it.
