You can't put a price tag on piece of mind when caring for seniors. My 83 year old father was very independent and still drove 2-3 times per day. One afternoon he went to pick up dinner from a local sub shop and was gone over 45 minutes. The sub shop was a 5 minute drive. The landairsea tracker helped us find my father. He simply got confused and went to the wrong restaurant! Best investment I've ever made.
