When going for a quick hike or  a run, this bracelet is very useful. I just write down my drivers number in it, contact numbers and of course, my name, and voila! I don't have to worry about my I.D. falling off my pocket while I'm out and losing it forever. Also good for camping. it came with 4 tiny strips of paper to write down your information. For about $14 a pop, I wish they included extra strips of papers, for one, phone numbers change a lot, and two, it's so tiny that writing down information, it is very easy to make a mistake and no space to correct it with. Also, do NOT go swimming with this on.
