A representative from Triangle Lifeline spoke at my church to inform us about the service they provide. What impressed me the most was that Triangle Lifeline is the only Medical Alert company in the area that has been around for over 30 years. When you call you get to speak to a person locally, not like the companies you see on TV where they want to mail out a unit and you have to install it. When you call Triangle Lifeline you speak to the person who will come and install your unit. If you ever have any problems they will come back at no charge. The technicians are polite and prompt and the best thing there is no contract.
