Love that it’s just one controller for both dogs and can be set at different levels per dog. I’ve been fortunate that my dogs respond to the vibration and sound to get their attention and I have never had to shock either dog.

Washed the remote on accident and still works. Love this collar. It work very well and give me the option to change strength of vibrate and shock.My only wish is that I could control it with an app. I forget the remote often.
