Kathy,
We now have one that protects Judy?s garden and our yard from the bears. They are not cheap, especially considering that it only takes one lightning bolt close to anywhere along the fence to blow it apart, literally.
I had 2 ac electric wire boxes blow the covers off with almost nothing left inside. They were in my old barn.
I later found that all of the 120 wires were hit. Every staple had burn marks and everywhere the wire made a bend, the insulation was melted away. Very unsafe.
