Title: Not a substitute for proper training
Review: I bought this just so I could review it and know what to recommend to my clients. I do love the system itself, but not this accessory. It won't do anything to discourage a puller and I can't see that it will do anything to relieve the constant shock of a dog tightening up on the leash. Good training will do more good for you and your dog. Buy the system, but leave this accessory off the list.
