Review on 🐶 Zelers Ultrasonic Bark Deterrent - Effective Dog Barking Control, Anti Barking Device, Bark Control Whistle, Stop Barking Training Tool (Black) by Clint Blackman

In the 10 days we have you can definitely hear the difference in our area! The dogs next door were awful! If I didn't like the neighbors so much, I would complain about the noise. This stopped 4 continuous barks on their way. However, there is one fatal flaw: I can't keep the battery in it for more than 4 days before it dies. That's a ridiculous amount of money to spend on batteries. If it had longer battery life or a wired connection I would give it 5 stars out of the box but for the amount of money you have to spend post purchase. Why bother? Maybe if MY NEIGHBOR pays for the batteries?
