Ok..so I received this today and it was used today! I was leaving my home and two neighborhood dogs were fighting. One Pit Bull and a smaller dog. The owners couldn't separate them. I grabbed the small dog and turned the unit on with the infrared towards the Pit. He immediately calmed down and backed away! Not sure if it works for everyone the same, but tonight, it worked for me! The two owners were thankful and quite happy. I like this item! Also, my daughters Boxer immediately calmed down when it was used on him! My daughter is extremely happy as well!

In comparison with a cheaper one with one emitter, less hear the human ear, while checked on the cat, reacts, but not as an old one. There is a mode just a flashlight. I ordered two, one button fails, I will have to open it.

The parcel came very quickly for about two weeks. The repeller works, the color black took very well heard when you lift to the ear. On dogs has not yet checked but I think that it will work. Thank you seller.

The device really works! Dogs shuffle and immediately run away, only the tail is visible))) only try not to guide yourself,. Because then in the ears a couple of minutes whistles) in general I recommend!

I do not understand how he works, passing by the dog sleeping she wakes up and snarls at me. Turns out the reverse effect. Instead of defending, on the contrary, he's turning to aggression.☹& Middot;
