Having grown up around chargers, I can tell you that kids learn quite fast to stay away, and I've never heard of any kids being permanently harmed by a jolt. I would think the circumstances would have to be pretty unusual to cause permanent harm.
They will, of course, learn to play with the fence pretty fast, daring other kids to touch it, pee on it, grab a weed off it, etc. [img]/forums/images/icons/laugh.gif[/img]
We have two of the Solar chargers (6v) that we picked up when Quality went out of business. One is protecting the wife's new goat pen and the other is still waiting in the box to protect beehives when we get them, (they work pretty good on bears).
