Came across this on a thread on another cycling forum, it looks like quite a good idea - especially as I'm out on my own on the bike quite a lot and about to start commuting at night. At the moment I have emergency numbers in my phone, but obviously that might get broken in an accident or be somewhere at the bottom of my bag where nobody is looking. Also, there is no way of putting in allergies, etc. so road id looks good - and I quite like the actual look of the wristband as well.

Does anybody on here have one? What kind of info have you put on it? Anybody ever needed it?

I need to work out the $-£ exchange rate, but I'm definitely tempted....Any views?
