"I received this device for Christmas and LOVE IT. I also purchase one for a friend. The USB holds all information I required and the additional metal plate states I am diabetic using insulin with heart issues plus two phone number and my name. When in the ER they were able to view my information, I did not go in an ambulance. However, I have been insured all EMS look for all kinds of medical alert information and have the equipment to use it. Most helpful when out walking to have all the information required."
