I was really against e-collars but this one is different than I pictured. The beep and vibrate function are all i use. The first time i put it on her and she did a behavior i wanted corrected i pressed the vibrate button while telling her no. That worked like a charm. After that all it takes is a beep and she listens immediately. She used to run out the door and take off. She did it one time and I beeped her collar and she came right back. Now she can go off leash whenever and she comes right away when called.
This is the one e collar I use and is one of the best on the market. I feel like I am in full control which makes me feel less stressed. Would recommend 10/10.
