Wonderful product.The collars keep our dogs in check.

One little shock is more humane than people yelling or (God forbid), even hitting their dogsIt has seven sensitivity levels to meet all of my needs, and is built very well.

It took some time to get familiar with the control bottons on the remote, when I did my dog and I really worked well together. At first I used the lower settings to get her attention and I got better at using the remote. After some time I could up the intensity and she responded to my training very well.

this collar was exactly what I wanted. Easy to use and prefect vibrate setting was just what I needed. There are three options noise, vibrate or shock. I have a mild dog so the noise and vibrate are all I need. He is 72 lbs and took notice of the vibrate right away.

Once I set the levels on the settings and synched up the collar and remote, it works perfectly.. No problems.

I have an English Setter puppy. Very active when outdoors. Can easily jump my neighbors chain link fence. Bought this collar as a learning tool to teach my dog that this is unacceptable. Took a while for him to get use to wearing the collar. But found that it works great. He has not jumped the fence in weeks.
