I got the LandAirSea GPS device to see what was going on with my disabled brother. He started using more cash than normal, and I feared that he was being taken advantage of by someone in his apartment building. (It had happened before.) Instead, he had just started eating out nearly every day. I've continued the monitoring just to be certain that if he gets lost he can be found without having to have the police issue a "Silver Alert" for a missing senior citizen. It gives me peace of mind.
