Review on Casfuy Dog Training Collar with Remote - 1000ft Range Electric Shock Collar for 2 Dogs: Rechargeable, Waterproof, Beep Vibration Shock: Small Medium Large Dogs by Brenda Garvin

I was offered a free additional collar or controller for a product review I declined this offer because I wanted to return these devices before their expiration date and give an honest review be able. I seem to see fake product reviews on Revain more often than ever. But I can honestly say that I have used these collars on my giant breed puppies and they have changed everything. even have to use the shock function. My dogs respond to the vibration feature when I want to change their behavior and it works like a charm. I'm using the sound function as a pre-stage, and now all I have to do is get her attention. I love this product. The range is good. Battery life is good. The only downside I can think of is that the collar tends to come loose, so you'll need to tie up the excess so it doesn't slip off. Great value if you have two dogs. The box includes a lifetime warranty card.
