Review on FOCUSER Electric Wireless Dog Fence System: Waterproof & Rechargeable Pet Containment for 2 Dogs by Kenny Marquez

This wireless dog fencing system saved us! Our dogs kept coming out of our garden and being taken away by animal control or neighbors - we have 3 dogs that use these collars and they are amazing. We've never had any problems and have been using them for over a year. It only takes a dog once to know that there is an invisible barrier and he will be shocked when he crosses it. Even if the battery is low, they KNOW the barrier and will not cross it. They were a life saver and allowed us to keep our dogs otherwise we couldn't keep them safely in the yard.
