in order to get this to work you have to use the test button. i bought a cheaper one on ebay and it works way better, less features...but the main feature works better than this one.

Works well for large dogs that have a resonate bark. Not so good with the little yappers though.

I have a small Shih-tzu who barks only when the neighbor's dog on the other side of the wall barks. I was hoping this would stop the barking of both of the dogs, but ultimately it didn't stop either dog from barking. Unit was installed per the directions, and triggered more from trees rustling from the wind or from me making a sound 2 feet from the microphone, but NEVER triggered from the dogs barking only 5-10 feet from the unit. Very disappointed in the effectiveness of this item.

The Bark Smart Deluxe is a big disappointment. The microphone simply is not sensitive enough, even when set at "High", to activate the unit's ultrasonic signal in response to non-stop barking from a dog that is 15 to 20 feet away. And the barking is from a young basset hound, so it is not lacking in volume. Yet he appears to activate the unit only when he is facing it and barking directly at it. Most of the time, the dog is barking in another direction. So long term, I do not expect the Bark Smart Deluxe to be an effective deterrent. I will say this though, when the barking does activate the ultrasonic signal, it is clear from the dog's reaction that he hears it. And clear that he finds it annoying. That part I like. I also like the activation counter feature; it is the reason I chose the deluxe model over the standard model. Without it, I would have had no way of knowing how infrequently the signal was being activated. It was worth a try though, considering the device was reasonably priced. Reasonably priced enough that I am considering buying a second unit and maybe even a third to try to cover more angles; I am that desperate for a solution. But again, I expect that one unit would be enough if the microphone was more sensitive.

I did not find that this prodect stopped my golden retriever's barking at all.

I think this would work well if there wasn't a 5' wall between the unit and the dog. It really seems to need an absolute clear path. I had it mounted about 6' up, but will need to try to mount it even higher to see if it works better.

This Bark Smart unit has a very serious flaw. When used outside it appears that the device is affected by overheating by the sun. This causes the device to lock up and stop working. The only way to reset is then to either remove the batteries or unplug the power adapter. Very dissatisfied with this product.

The bark smart works great, but one note to users is that if you are using it for a neighbor dog like I am, be sure there are as little obstructions as possible, it is best mounted on a pole to emit the pulse over the fence The newer models will hopefully vaporize the dog !!

I should have listened to the other reviews. This product is worthless. The barking dogs drove me to go against my better judgement. I tried the product the very day it was delivered. I was soon on the phone with Smarthome in order to return it. If you do buy it, you should know that Smarthome's customer service representatives are very nice and easy to work with. My money was returned, less the shipping, within a week or so. DO NOT BUY THIS PRODUCT.

While this product does work, it has trouble "hearing" some dogs. It has a lot of features, but it would be better if it could hear barking better. I placed it in the yard with a dog that barked all day, but it only triggered three times.
