I had a "free" one offered by my Medicare intermediary (age 80).  My thinking was that the idea sounded good for someone living alone in a rural area.  After 2 weeks, I turned it off and tried to return it.  The Medicare intermediary wasn't interested.  It was disassembled, then put in the trash.

Problems:
1) False alarms.  My contact person (daughter) ws worried to death.  She survived.
2) Rural community, trees, and medi-alert do not work well together.  Most of the time there was not 2-way communication, hence the false alarms.

Solution:
I send an email when I start some dangerous thing outside, then cancel the alert to my contact person when I am done.
