Well I got mine today and put a 9 volt in it and waited...LOL.. Don's friend came by and I used it and said "quiet". Everyone quit barking except Mindy. However she only barked a little. each time she made a sound I used it and gave command, it did work. Figure a few more times and she might stop for good.
It seems to work on some of the dogs and not at all on a couple others. the 2 youngest ones didn't seem to hear anything. It has my cockapoo Ripley and yorkie Kizzie, freaked out! They hid, and Kizzie it made her shake.
This thing has very short range. I couldn't get any of them to respond when I let them outside and they were going nuts barking at another dog. NO effect at all and I wasn't about to go out in the rain so I stood on the deck, I was maybe 20 feet away, still no effect.
However I think it will help A LOT for the constant barking at nothing all day like they have been doing.
Will give another update later
