Review on 🐶 Alysontech Bark Control Device, 2021 Ultrasonic Anti Barking Device for Dogs - Dog Behavior Training, Sonic Deterrents, Outdoor Silencer to Stop Barking by Sharon Griffin

This device has caused so far: constantly running air purifier, ceiling fan slow that makes no noise, I go to bed and I suspect air molecules the way it worked several times for almost no purpose. It also gets away with barking, but isn't particularly effective at reducing barking if it's heard all the time. There's no way to lower the sensitivity, so basically we just leave it off unless the barking starts, at which point we turn it on. This is then effective, but largely defeats the purpose of an automated device.
