The battery life on the is product has been great. Also like that it will grow with our dog. The lock feature is a wonderful feature to have as you can accidently hit the buttons if it it is not set.

Good quality for the price! Easy to operate

I really like the battery life. It lasts way longer than other collars I have tried. The vibration is amazing. He listens but it doesn’t hurt him.

I have a very uncontrollable dog. He was just a puppy and very rambunctious. Previous owners kept him cooped up all the time. This has been a life saver! The battery is easy to charge and lasts forever.

The NVK works great, no need to use the shock, just the vibration or beep controls my pet perfectly. And come strait back to me.

Our dog has turned into the perfect girl after we purchased this collar. We mainly use the vibration and the noise to get her attention. We use it when she continues to bark or tries to jump on people.
