I've had my basic one for a year now. Mine is so basic that when I had an issue with one of the contacts on it, I took a sharpie and crossed out his name and number I love the basic because it allows a loved one to know I'm in trouble at the same time as being able to convey important information about me to a hospital or whatever.

Don't forget about putting emergency contact numbers under (In Case of Emergency) ICE 1, ICE 2, .... in your cell phone address book. We were informed of this in Georgia; don't know if it was a national thing or just local.
