Review on PetSpy P620B: Waterproof Dual Dog Training Shock Collar with Vibration, Electric Shock, Beep - Remote Trainer for 2 Dogs, 10-140 lbs by Allison Carpenter

My first training collar wasn't easy to use and the battery life was too short. That's why I decided to buy another collar and I have no regrets. This product deserves your attention. Well made collars and remote, they look really solid. I've had them for 3 days now but my dogs have already changed. From day one I haven't heard any annoying barking from them. It's really awesome. Without a shock, just with vibration, the dogs stop barking immediately. Now we're working on the ditch. I am so happy with my purchase! Highly recommended.
