I received my PetGentle about a month ago. My dog was barking and howling to the point that I couldn't even speak to a neighbor when I was walking her. Since I started using the device all I have to do now is show it to her and she stops barking, howling or whatever bad thing she is thinking of doing. I wish I had one of these when I was trying to train her when she was a pup.
Bottom Line: Yes, I would recommend this to a friend
