The health care proxy of a close friend who is 81 and lives alone suggested that she get a life line. She resisted (ordered one and sent it back) so I decided to look into them. She had done the research and I selected MobileHelp, telling the salesperson that I wanted the “Cadillac model.” Once I got it, my friend followed. I think it is the best on the market. I have fallen once since I got it doing something stupid at the pool (got up without a problem) but the fact that I fell convinced me that I had done the right thing in also getting one for myself. It does provide a sense of security which I think is important. It was easy to set up and is, I think, easy to use.
