We tried another barking mechanism and it was a phony. This one actually works great. We know this one emits a sound because it sets off my hearing aid. Thank u

This product works great and was delivered internationally. Much appreciated

I had a deterrent like this years ago but lost it. I needed a cheap replacement and this hit the spot. Highly recommend

Bought this to help my dog stop barking when he shouldn't be. I set it up in my den where I watch tv and read often. When my dog barks, the box lights up and calms him down while I am unbothered. Glad it works, well worth the money.

I don't like my dog wearing collars 24/7 and this device allowed me to set it up and forget about it while it manages my dogs excessive barking. Similar products exist in a collar format but it's clunky and needs to be charged often. The price of Sonic Barks device was cheaper and the quality was the same, if not better, than other products I have tried. I returned to buy a 2nd device since I needed one for my yard as well as my house.
