Works well on the tone, vibrate and shock. The two levels of shock are slight and moderate and certainly not enough to hurt the dog. Well priced and functional unit to train you dog.

I have a four year-old chocolate lab who is showing signs of regression when it comes to his home training. I was referred by a friend At first, I was 100% against it because I didn’t feel comfortable with the idea. Upon reading several reviews, I decided to opt in. This product comes with a collar, remote control, and charging cable. I was actually really impressed of the quality. There are a couple of options on the remote control, my favorite feature is the one where I send out a warning beep before vibration, that usually gets his attention. I’ve only had to use this once, my dog did a 180. Glad I purchased this product, it’s a great reinforcer.

My dog is trained to correct with beeps, so I can't speak to the effectiveness of the vibration and shock. This kit has very long battery life, long range, and is built well. The beep is loud for the dog to hear and respond, but not startle too much.
