We have loved this. It gets his attention as needed, we don’t use it often, but it’s a great all around dog training collar. The shock is definitely strong.

The shock adjustment is really good for when she doesn't heed previous warnings. I prefer not to use the shock though and most of the time the vibration is strong enough that it grabs her attention and makes her listen.

For use on my German Shepherd. I have had to use the shock very sparingly since he knows that the vibration means he is in trouble and the vibration is strong!

Nothing to discourage away from purchasing again. that works great.

Easy to use. Instructions are easy to understand.It has a buzz and vibrate option which we have used. Haven’t used the shock portion, our dog took to the buzz and vibration to correct his behavior.

This is a strong dog training collar and very easy to use.
