Something to consider when we look at any "training tool" is what it is designed for. Is it really a "training tool" or is it designed to force an acceptable behavior on the fly, without really teaching the dog. As you work with this collar, ask yourself if the dog will be able to walk, infraction free, without it, after a week, a month, a year... If the answere is "no" , then it might not be for training...It imight merely be a restraint. Do you want to teach your dog and inhance your relationship or do you just want to coexist? I haven't seen the product so I don't know about it specifically. This may be a good way to look at any new device.
The popular Gentle Leader is often misused by folks as a management tool. (I'm guilty of this myself.) But with TRAINING, it can be priceless! This new collar may be a phenominal training tool...but you have to train to make it that way. I always tell my clients, "The purpose of ANY training tool is to GET RID of IT!!!!"
Good Luck!
