I'm Amazed! He went from being like a "Marley and Me" dog to "Insta-Manners" dog! Easy directions and set up. Have only used it a few times since purchase and just as advertised. I look forward to trying it out in the summer at the beach. Very happy with this product.

The logistics is very fast, my dog often barks, affecting others, so I am very anxious to use this dog collar, so with the mentality of trying to buy a dog, the effect is very good, my dog also like this collar, very easy to use.My dog is good now and I like it very much.

I am very impressed by this collar.It does what it says and saves me plenty of headaches. My 6 month Pit was chasing the cats and barking like mad. Excellent Product. Highly recommend it.

Very pleased with the NVK Dog Training Collar. We have a wonderful, excitable Bassett Hound who loves to play with our older rescue to the point of exhaustion. It in invaluable in preservation of our rescue’s mental health! We only had to vibrate it once. Now just putting it on does the trick!

The whole set up is easy to use. It was well thought out. The shock is a lot stronger than other collars I’ve used which is good for my stubborn dog. Granted the vibration is used 99% of the time when needed and it’s enough on the low power settings.

Bought this to help train our mini aussie border collie mix to respond when running off towards people. The vibration strength easily gathers her attention and the lock feature is nice as I put it in my pocket frequently. The charging cord conveniently has plugs for both devices. Happy with our purchase.
