Review on Ultrasonic Dog Barking Control Device - Sonic Deterrent for Bark Control - Mini 🐶 Repellent with 50 FT Range - Silencing Ultrasound - No Bark Training Device for Dog Security by Michele Olson

I am very satisfied with the product. Old grumpy and noisy gold next door rarely barks outside. I used to have a wearable device but wasted too much time pointing to it and sending out a signal. Now I have a UANAX dangling from the end of our patio cover on a small hook that faces the neighboring garden and I turn it on in the morning and off at night and that's it. I was so skeptical before ordering but plan on buying another one as a backup if this one ever breaks down.
