Bests & Worsts Reviews from Amazon

I normally do not write reviews, I should be better about it as I read them before I purchase, but this one I have to take the time to write. I cannot say one thing negative about this product, not one! I have a sweet Yorkie, but she was a barker, mostly when I walk her, at other dogs, birds, people, you name it. She does not have a mean bone in her body but the barking was annoying for others and for me and was exhausting trying to keep her quite. I saw this little gizmo and decided to give it a try, I am so thankful I did. I read through the instructions thoroughly, and from day one, it solved my issue. She never even made it vibrate I don't believe, just the tone was enough to reinforce my "no". Living in a large condo community this is such an asset for me and for her, she gets a lot more pets now that folks are not concerned with having their hand bit, she use to sound foreboding . I would very highly recommend this to anyone trying to train their good dog not to bark so much. My only regret is that I did not find it and purchase it much sooner!
