Parents, I am telling you; this is a good way to see where your love ones are incase if something bad happens, this system can save a life or provide assistance ASAP when need to. GPS enables you to locate the phone and the location of the person that carries it. Yes, this maybe very good or bad  but I would prefer to have something like this help me find my kids, family, friends in hard times.
 
These phones they also have walkie talkie technology besides GPS, they are great tools and the price is right.
 
Hope this information is useful and YES technology can help and enable us to do better and greater things.
