I'm giving this product five stars because I believe it is a quality product. It was well built and actually looked nice. However, it didn't work for me. I was using it in an environment with two shelties and a border collie who go bonkers over anything and feed off each other. They are also in a garage with a concrete floor that probably amplifies the sounds. I think there was so much barking that they could never hear the sound. I would recommend that you try this product anyway and see how it works for you. I think my problem was a fringe case.

I turned this thing on and all but one of my dogs promptly shut up and walked away. It has no effect whatsoever on one of them even on the highest level. I don't even mind, I take it as a win either way since it works on the majority. I've used to to break up dog fights and to keep them quiet when they get out of control out in the yard over squirrels and won't listen. I'm very pleased with this purchase.

If you or a neighbor has a barking dog, this is a must have. Neighbor dogs bark constantly. Turned this baby on and the leader of the pack barked once, sort of shook his head, barked agan and said to himself "what the hell was that"!. Now they run to the other side of their house whenever they see us. BEST MONEY SPENT EVER!

It didn't do as well as some I have had in the past.

Omg best thing ever. Neighbors dogs barked every night from 9-11 and every morning from 6 to at least 830 when I left for work. Installed this thing and within 3 days had both of them trained not to bark during the night or morning. Highly recommended

Has done little to quiet the dogs bothering us.

not sure if it was working or not but it did not effect my dog at all. Ended up buying a anti-bark collar.UPDATE: As mentioned above, first unit did not work, vendor sent another unit and it works fine.

We have 3 small dogs, it only worked of 1, when the other barked it mad the 1 very scared, she was a wreck all the time, had to shut it off! Worthless if you have more than one dog!
