Apparently these watches not only act as a tracking device but will send an alarm if your child goes out of a pre-defined range!
I did wonder if the parent has a corresponding device which can send an electrical "zap" if the child does this.
Or am I being wicked?
I suppose there will be a market for these but not sure I'd use one. Might be good if you have a child who wanders.
A friend of mine whose son is autistic has terrible problems because he wanders off - her attention can be taken for nano seconds and he will be gone. She has got around this by giving him a mobile phone which he will usually answer if she can't find him. On one memorable occasion when in town he disappeared - she was frantic, the police were called to help, he wouldn't answer the mobile and eventually he was found nearly half a mile away looking at the televisions in a shop. Horrible experience for my friend and so I suspect she would love this device.
