I firmly believe that EVERY Senior have a medical device to be able to get prompt, knowledgeable service. Ever since I obtained a Mobile Help system, I have been assured of this service. I have picked a day of the month to press the button testing my system, and each time the person(s) answering the buzz has been courteous, helpful, pleasant and eager to be of service. For me, on a fixed income, the cost is well worth the service. Anywhere I am, if I need help, I can reach someone who will know where I am, have medical history available and good sound medical advice. If I need to get to the ER, they will send an ambulance/aid car/fire truck to my door. I will be able to be helped immediately. I was even given a key box with a code number on it to hang on my outside door; it has an extra key inside in case the apartment building manager is gone for the weekend. I really love my Mobile Help System.
