I've just bought new bracelets from pfo for the whole family. But it's not normal bracelets even if it may look likte it. They actually have a small gps device built in them. So you can actually track the person who wears the bracelet. So no more worrying where the children are late at night. Now I can track them if I need to. I have to say that I'm more comfortable letting them go now. And they are glad that they have more freedom now. So I can really recommend these bracelets.
