Have to say I'm quite biased on this one, but I would go only with Multimedia File Viewing and Clickable Links are available for Registered Members only!! You need to

Yes, there is a yearly membership fee, but for that, you get a whole lot. I've been going with them for years now. Previously, I went with companies that allowed you to put your info on a bracelet, but whatever you put was all they'd know. With Medic Alert, you go in online or via phone and update all allergies, conditions, medications, and emergency contacts, and then between Medic Alert and you, you decide what you want the bracelet to say. Personally I have way too many things going on to just have them take my bracelet at face value. My current bracelet says "Multiple Medical Conitions, Multi Allergies, On Medication" and has my Medic Alert ID# an the phone number for Medic Alert. All a health care provider has to do is call the Medic Alert #, verify that they are a health care provider, give them your ID, and they receive a print out of all the info you've put into the database about your health.
One of my older bracelets says something about my anaphylaxis to benadryl and to call medic alert. The newest bracelet I will be getting will say something about my implanted stimulator and multi allergies, and to call medic alert.
Medic Alert also has something called an E-Health Key which allows you to cooridnate and store all kinds of info on a USB that can be used in any type of computer by health care provider. I have one, but am not currently using it.
Personally, I like Medic Alert based on the companies where you just get an engraved bracelet, but that's because I have pretty complicated health issues. They do have ways to help with the cost so that nobody goes without a bracelet that needs one. I got a pretty cool beaded bracelet for cheap...about $25. But they have some pretty fancy jewelry for those who would be interested. They'll also send you a card with your major health info on it for your wallet.
If anyone wants to know more about my personal experience with Medic Alert, I'd be happy to share. I really like them. For awhile I'd let my membership kinda die off, but then when I got my stim I just renewed it and wear my bracelet every day now. I have fatal allergies to a couple of meds, so I really have to have the bracelet on me at all times.
Just my 0.02!
