Already ordered medical alert necklaces. I did not want to add a bracelet, but still wanted something which would give information in case of an emergency. I like this because it allows me to give additional information which might be needed. It is handy as I am seldom without my cell phone. It is not intrusive as only need to provide information in case of an emergency and not necessarily otherwise. I do enjoy my necklaces, but find I can't have too many items which give information in case there is an emergency dealing with my health.
