This collar is exactly as manufacturer describe it, so I can't fault them too much on that. However, I found it to be FAR too sensitive to be useful.To elaborate a bit on that, this collar definitely went off every time my dog barked, so I guess that is a good thing. Unfortunately, it also went off every time my kid made a loud noise, every time my dog jumped off the couch and landed on the wood floor (not that loud), every time the doorbell went off, etc. It went off and "punished" my dog for things that were not barking and not what it should have been responding to.
The only place I found this device to be useful was placing it next to my dog's crate at night when there weren't other noises that would make it go off. It did seem to help a small amount in keeping her from barking at night while she was in her crate, but after a while she seemed to just get used to the noise and simply ignored it.
If you are looking for a device that will bother your dog every time there is a loud noise in your home (or outside), then this is a great product for you. If, however, you are looking for a device that will help you control your dog's barking by creating an association barking and a disturbing ultrasonic noise, then this is the wrong product for you. Your dog won't learn anything about barking by wearing this, he/she will simply learn to hate all loud noises because they are immediately followed by an ultrasonic tone...
