Here is a "tool" that our difficult children do NOT need, but at times would be tempting to use on our difficult children, lol! http://budk.com/Self-Defense/100000-Volt-Stun-Gun?sourcecode=woot yes, it is a real Stun Gun for just $9.99!!! I never thought I would see one at this price - talk about prices being crazy (in my opinion)!! While it might be handy if you must walk or be in dangerous areas at night, I am not sure it would be a good thing to have in a home with a difficult child. Would you have a use for it??
