Review on JZORI Ultrasonic Deterrent Anti Bark Ultrasound by Michael Rosario

I do not write reviews. As usual. If like us you have a problem with a barking dog, look no further. Our dog likes to bark when our backyard neighbor is on the other side of our fence. We love our neighbor and are very ashamed when our dog keeps barking at him while we punish him to stop and try to talk him out of barking at the fence. We tried vibrating collars and they worked for a while but now he doesn't care. Actually, I had considered using the shock setting. We got this thing a week ago and it's generally quiet. That's wonderful. Released him yesterday without that damn bulky collar, no squeak. Well, actually he grumbled a bit under his breath and then gave up. If this continues, we will be very happy. We were on the back deck last night without plugging it in once! Finally something works! Fingers crossed! Update: as of 10/23/20 still works. I agree with everyone who suggested getting a 9V battery - they need a new one every few months or so, but it's worth it.
