I purchased for this for my Aussie because he will NOT stop chasing the neighbors cat. After a few times of using the beep, vibrate function he has stopped! We have not even needed to use the shock feature for that purpose. We have tried the shock when he went after someone on a bike and he yelped and came right home. He has since learned when we have the remote in our hand what will happen if he does not listen. Its worked great so far and have not charged it since we recieved it 5 days ago. Its still going strong!
