Works well so far. No problems that I have experienced. Will update review with more use.

This collar has worked well for my puppy. We only use the vibrate setting, never the shock but it has great distance and really works well when you need to get their attention!

I used for my puppy Pitt bull. It was easy to follow directions for set up.Easy to set up directions and ready for use. Easy to adjust and put on your pet.

Tested on myself first (yes, the static) and it got my attention quickly with no discomfort. Have been using the audio and vibrate mode only so far on my dog, very responsive and long battery life.

This shock collar works! Now when I call “come here” he stops running to the street and comes back to me. I’ve only used the shock button twice. The other three times I used the beeper button. Amazing!

It took one beep and one shock to correct my puppy’s behavior. I have two other dogs and when they hear it, they all correct themselves. The instructions were easy to read and understand too. I’m buying two more for my other dogs. Safe and effective product!
