A friend of mine recently lost her pre-schooler at the mall. They ended up finding her pretty quickly, but as she was telling me the story, she said she wanted to invent a child locator device. I remembered a similar product I had seen on TV:

When I was young I got lost at the mall once. A nice man hoisted me up on his shoulders so I could look for my mom. These days I would be so worried in a situation like that. My friend is totally sold on this product and is going to buy one. Would you buy one of these to keep tabs on your LO?
