Great!!! very simple to set up with the instructions! Excellent product thus far. My dod changed her manners in just a few minutes!

So far it looks like will work very well for our little dog. Only used the vibration setting but it stops his barking

Our new puppy, Brooklyn, needed some hep with his manners. The NVK collar was a lifesaver!

I really like the product. I use it on my dog because I couldn’t get her to stop jumping on people or barking, it has really helped.

Lock feature is very handy. Mostly use the vibration and sound, and our dog seems to respond quite well.

Super easy to use and works great! also my dog listens now, really helps, i would recommend to my friend
