The works great and has a longer battery life than other brands I have purchased. I love that you can control the vibration strength.

Lock button is a plus, battery lasts forever, vibration strength is more than enough for your dog if my dog can feel it and it's on level 2 out of literally 100!

Out of the box I had immediate response. My dog was out of sight and not coming when called. One short hit on low he was at the back door. Good quality and easy to follow the directions.

This has been a great training method for our rottie. Never have to use the shock. She responds with sound only. Wish i did this with all my dogs

Training my dog to not bark at every little thing in the house and the people in it. Works great only use it once or twice a week now he has learned very quickly what happens.

easy to use, battery life good. have been using since mid december. only have had to use sound and vibration to get pets attention. i have 8 acres and works even when our dog is several hundred feet away.
