MobileHelp won't like this "revue," because I am disappointed. I seldom use only the main electrical unit and the item that firs on my wrist. I WAS excited about the "fall protection," but I am most vulnerable of falling when I get into the bath tub, but the pendant is NOT WATERPROOF,so I do not use it. Before I am mailed a third time for equipment I do not use, it is my desire to returned equipment in order to not be billed a third time. I accidentally set off the alarm and you quickly responded so I feel that if I do have a fall, your equipment will be very worthwhilke. Sincerely, MILES RUTHERFORD 807 Presley Way Sugar Land, TX 77479
