Peace of mind is of great benefit to a senior citizen living alone. If I never need the service I would still have been free of worrying about possible accidents, sudden illness, fainting, etc. A toddler visiting in my home found the base and the large red light was an attraction. After he pushed the button I saw how quickly Mobile Help was in contact with me. Actually my granddaughter answered the Mobile Help call and I was impressed with how thoroughly she was questioned about my condition and possible need of help. I have encouraged many acquaintances, particularly those who have fallen while alone and help was not received for varying lengths of time. I don't understand why they will take such a chance since they could afford one of the plans. I take the GPS with me even going to the grocery, to church, every place I go since I do drive. Makes me feel safe and relieves my family of concern. Pendant or bracelet (at night) worn 24 hours a day.
