It works really great for me. My hound is a bit too sensitive to any loud noises so when it is on, she cowers and shakes and wants to be inside, but she doesn't bark. It stops my GSD just fine. When it is on, I have noticed the light that flashes to indicate it works can go off with talking or even loud jostling sounds. I don't recommend leaving this on 24/7, it will eat battery like crazy, and because it is so sensitive, I think it is unfair to hit your dog with supersonic noise when you are the one causing it to go off. It also "pings" when they are growling and wrestling, which makes me feel terrible. I think it would be best for a single dog if you don't want to be judicious with your use. Or just be a good dog owner / neighbor and turn it on in response to barking, but off when it isn't necessary.

Meh. The neighbor's dog certainly noticed this, and it did reduce his barking in the first few days, but after that, he just barked right through it and the device had no effect. (Outdoors, 15'-20' distance, aimed exactly at the dog.) This device has a 3-position sensitivity setting (how much noise is required to trigger it), and that's good. What I really WISH it (and other devices like it) had, is an *intensity* setting, where you could ramp up the volume (i.e., irritation factor) to the dog. I don't want to be cruel to dogs that need less irritation, but I DO want to be able to turn it up to jumbo industrial strength OMG what the #$%^* is THAT?!? for dogs who need it.Ultimately, this device didn't work in my situation. I think it's extremely dependent on the specific dog and circumstance, so I imagine your mileage will vary greatly.

Worked for one week, seven nights, set on 'low' and used only at night. Turned 'off' during the day. Night eight the dog ignored it and barked all night. Put new battery in, just in case. (The indicator LED was still green) On night nine set unit on 'high'. No barking for about four hours, then barking for the rest of the night, and ever since.Ether unit is defective, or the dog is deaf! Since he responds to voices I don't think he is deaf. A bucket of water would probably work as well. Should have sent the unit back!

Maybe worked the first 5 minutes. Dog bark at the "noise" more than before afterwards. Very disappointed with the product.

My neighbors have a German Sheppard puppy that barks incessantly when we are in the yard and they won't take it in or train it. I got this and take it in the yard when I'm outside. It works great. The dog starts barking and then you can tell he hears it and he stops. I'm hopeful it will teach him not to bark at us. Great buy.

Interesting product. Worked for a little while, but our loud barker just ignored it after a short time. Seems to function correctly, but totally ineffective at stopping the barking.

This item didn't work or I thought it worked just long enough for the seller to refuse a refund!

Very small and works great. I sleep better and have more enjoyable days now that I've got this divine outside my apartment to stop my neighbors dogs from barking. I highly recommend this item. It's much more discrete than the birdhouse style.
