Title: minimally effective
Review: THis product produces an anoying loud buzz. It did not control my dogs barking. I did better putting them on a sit-stay for a a minute, rather then use this product to reduce barking. Remember if you buy this product you must be in the room to reinforce behavior to get your dog to quit barking, if not your dog will get used to the noise and you will having a barking dog that also makes a loud buzzing noise
