The best purchase I have made for my dog in a very long time! I wish I had bought it sooner.We used the indoor radio fence to keep the dogs out of parts of our house. He was already use to the beep warnings and new right away to back up. We wove the wire into a chain link fence that my neighbors on all sides had. Brought it around the front of our home, and through the cement separation in our drive way. It's very easy to setup!
