Bests & Worsts Reviews from Amazon

Collar works great. After reading the instruction manual, watching the youtube videos noted in the instruction manual and properly fitting the color on my dog, it only took a couple of times for my dog to stop barking. He now hears the beep and stops barking before the vibration starts. It worked so well on my Yorkie that I out the collar on my Maltese and my Maltese stopped barking after 3 barks. An added benefit is when my Yorkie hears the beep while the collar is on my Maltese, he stops barking as well Update: The dog collar stopped working shortly after the 1 month warranty period.
