Review title: Not worth it
Product review: Worker great the first time, then never again. If you have more than one dog barking they easily get distracted by one another and just bark over the device. Only noticeable to the dog if things are quiet and nobody is talking, and no other dogs are barking. Otherwise, waste of money
