"A very comfortable fit and design was what caught my eye. I have needed to wear a medical alert identification since the 80's and I have tried many styles all over time become uncomfortable and they are not water proof. Nor did the other Alert bracelet or necklaces carry all your medical information for emergency services, they would have to call a 800 number to get your full medical information. If you used Medical Alert you had to pay a yearly fee and send them in writing any changes to your medical history. That was a real hassle and added expense. Since I have had the bracelet my doctor has already changed one medication and I just plugged in computer and update. Plan on ordering one for my husband and dad."
