Honestly, I have only used it one time. Only one of my three dogs started barking at a car that pulled up in the driveway. The other two were elsewhere in the house. She was facing the door barking, I picked up the BarxBuddy and hit the "On" button, which was set to low. She immediately stopped barking and turned around to look at me. I told her she was a good girl and gave her a treat. I am looking forward to using it to help my other dogs curb their enthusiasm! Thank you.
Bottom Line: Yes, I would recommend this to a friend
