Review title: NO GOOD!
Product review: I purchased this product after reading mixed reviews, Let me tell you that it should be illegal to sell this scam. I have 4 dogs of several breeds and this product never seems to affect them at all. Yes I keep fresh batteries in it but thats not the problem. This is the worst product I have ever purchased from Amazon.
