Medical alarm with GPS for elderly family members

I got a medical alarm with GPS for my dad after he wandered off from the grocery store parking lot. Now I can see his location on my phone, and he just presses a button if he feels dizzy or lost. It's a simple pendant that gives him freedom to walk the neighborhood and me some peace of mind.
