When I got up in the night and was taking a walk to the bathroom, my walker somehow got tangled up in a small rug and I ended up on the floor. I could not seem to move, and couldn’t get up. After a little time I remembered my necklace and I pressed the button and a very nice voice came out and asked if I was in trouble. I assured her I was! She then took care to call my friends who came right over. And now I am well for a 95 year old lady! Thanks to your help.
