If you have children, read this thread

Parent of two boys here, and one of an age that the product would be good for.

As a parent, I really like the notion.

One thing that came to mind when I read though.

I think you'd want to make it so they could add skins, or do whatever to disguise what it is. Not so the kids will buy into them as being trendy and cool to wear. (though that isn't a bad thing)

But what popped into my mind was this. Someone has been watching this child they want to grab. Say they planned to molest then release. And they grab the child. And they see that the child has one of these devices (imagining that it is obvious as to what it is) So the plan now becomes molestation and murder, because they freak thinking the police are going to show up.

I may not have worded that well, so my apologies if it isn't clear. But I see reasons to make the device as inobtrusive as possible, and they don't have anything to do with getting your child to wear it.
