I picked up one of these ID's, got it yesterday and it looks great. I am wearing it today to see if it annoyed me, and I don't even know its there.... feels like a watch, but without the time.
It's a very simple idea, very inexpensive, and their site is easy to use to choose what you want on the tag. I figured for $20, if it saves me a few minutes to the E.R. in a bad situation, it's worth it. If I never need it, GREAT!
I went with:
Name, DOB
Town, State, Zip, USA
Home phone/wife's cell
Parents' number
Asthma / O-Postive blood type
Allergic to Amoxicillin
With all the outdoor stuff that I do, MTB riding, road biking, hiking, motocross, motorcycles, skiing, etc - you never know....
