Keeping track of a teenager often involves a keen mind and a sensitive nose, but thankfully we have the people-buddi GPS system that helps you keep track of your family no matter where they are. Small enough to be tucked into a pocket or backpack, the people-buddi GPS system uses both GPS and GSM technology to keep you informed of the individual’s whereabouts that can be accessed via the Internet or the company’s customer support line. The people-buddi isn’t cheap though, retailing for $600 a pop and requires an upkeep cost of $40 per month.
