Review on 🐶 ET-300ZEN E-Collar: 1/2 Mile Remote Waterproof Trainer Mini Educator with Static, Vibration, Sound Stimulation & PetsTEK Training Clicker by Chelsea Martin

This is the exact same item as sold in stores. It works very well. Easy to use, easy to teach boys what a simple vibration warning means NO. My GS is 5 years old and he figured it out right away. The puppy is 4 months old and I thought he had no hope haha. As soon as I put the collar on, he behaves 70% better even if I just put it on. Highly recommended. Also, don't just electrocute your dog - if your dog doesn't know basic commands then there's no magic bullet. Everyone. You have to do the work yourself. Watch some YouTube videos of dog trainers using this tool and use it properly.
