Lew has no use of his left arm or leg. In Dec of 2014 I purchased a "fall" pendent system for him. It has performed as designed, until it did not! Wednesday he fell on his patio in Lake Havasu City, Az. 90 degrees outside, he laid in the sun for more than an hour before his wife found him. She had been at work. The "fall" system failed, the button on the pendent failed. He pressed it several times as he lay there unable to help himself further! I'm not sure how to proceed, I have spent about 1100.00 dollars now (two years service for my mother who is ninety-two, and on year for Lew, who is handicapped) I'd like some consideration. Any thoughts? Sincerely, Ted A Manning
