Review title: Worthless
Product review: I purchased this product in hopes that it would keep my 4lbs Chihuahua from barking and whining in his kennel when I'm away. I placed the producted less than 3 inches from the kennel where my Chi usually sits. The product doesn't even detect a bark! I tried it out myself by barking and yelling at varying distances from the receiver and it does not detect anything until I have my mouth practically ON the receiver. Only then does it work. When he barks, it doesn't detect it, regardless of how close he is to the product. And with that, there's a test button to press to see if your dog reacts to the ultra sonic noise - my Chi being right next to it only perks his ears. Other than that, it has no effect. Do not waste your money on this product.
