Review on MODUS 2-in-1 Bark Control Device - Ultrasonic Dog Training Tool, Large 16.4 Ft Control Range, Safe and Effective, Dog Silencer and Whistle for Anti Barking by Justin Hollins

I have to admit I was skeptical. I have 3 Yorkies and when someone comes home it's like living in a kennel! Paradise, paradise, paradise! The first day I used it, it felt like a miracle. They stopped barking and looked at me confused. I've been using it for a week now and they understand that when I reach for it they should stop barking. By my calculations, this reduced my barking frustration by 75%! I'm still in shock that such a simple device works so well I stop screaming! Now if I can make it work for my fighting kids!? 😉Buy, it's worth it!
