Bests & Worsts Reviews from Amazon

Did NOT work for us. We ordered two devices but only tried one. The device functioned properly, and we followed the directions exactly. It did not pick up the bark for our neighbors' small, yappy dog, thus the device was not triggered and did not deter that dog. It did pick up the bark of our neighbors' large, loud dog, but that dog quickly acclimated to the device - even when changing settings. We returned the unused device to Amazon. The other device, unfortunately, was not returnable. The packaging (very tightly glued flaps) basically renders the box completely destroyed after opening. We can't return the device to Amazon in that state, and the company refuses to accept it for return. The "No Bark Guarantee" featured in the product listing (see photo) is not being honored by the company. Beware: If this product doesn't work for you, the company's guarantee is worthless. You will not get your money back.
