My dogs would always dig under the fence and escape. I work over an hour away from home at times, so getting a call that someone found my dogs was always a headache. Installing this did fix my issue after training the dogs and showing them where they should and shouldn't go.One thing I do recommend is having a game plan for installation prior. I was expecting to be able to just wire my backyard. But, after reading the instructions, I learned that it is not exactly easy to do - especially if you don't want any above ground wire.I used PVC pipe as shown in the pictures to hide the wire. I saw some reviews that fed the wire to the indoor outlet through a window (instructions say to use an indoor outlet due to weathering issues). I couldn't do this as it would prevent my window from shutting, so i drilled a hole in the hardiplank and into my laundry room.
