Bests & Worsts Reviews from Amazon

I have to admit I was skeptical. I have 3 Yorkies and when someone comes home, it's like living in a kennel! BARK, bark, bark! The very first day I used this, it was like miracle. They stopped barking and looked at me with puzzlement. I have used it for a week now and they realize when I reach for it, they have to stop barking. I estimate this has curtailed 75% of my barking frustrations! I'm still in shock that such a simple device works so well I don't have to yell anymore! Now, if I can get it to work on my arguing kids!? 😉 Buy this, it's worth it!
