We got the Life Line for my mom after she fell 2 years ago. I believe she pays about $49/mo. It is worth every penny. She wears the necklace around her neck 24/7. (They also make a bracelet type). Works anywhere in the house. During the bad North Eastern storm she lost power & phone, and they called me to let me know. Of course I already had her safe and sound with me, but it was reassuring to know they were on top of it. She periodically gets calls to check the system. If she pushes the button and the operator is unable to hear her, they will contact emergency services, call me and continue to talk to her thru the intercom which is very reasuring. During a recent hospitalization they tried to contact her thru the intercom while I was alone in the house. Scared the daylights out of me! But she's used to it, and somewhat hard of hearing so it doesn't bother her. I highly recommend the service.
