Well worth the investment. I am very thankful for the [Life Alert] agent that handled my call. As it turned out I was having a serious appendicitis attack. The agent was very professional in every way, and stayed on the line with me until the paramedics arrived and contacted my emergency contact immediately. Within 12 hours, I was in surgery having the problem corrected. I want to extend my personal thank you to that agent for the job well done. M.M., Albuquerque, NM
