I gave my review 5 stars, even though I am critical of a couple of issues. I have already had to use the the alert service, though I have had it but a few weeks. The response was just what I expected-quick pickup, prompt ambulance dispatched and a family member notified-all within 5 minutes. I do have a concern that the pendant has to be charged every 24 hours or so, making potential need of it unavailable for up to an hour. I am also disappointed in the unattractive look of the pendant and the black cord, which gets wet when showering and dries slowly, giving one a damp neck and shirt.
