I don't know if I'll ever event again, but if I do, I'd also rather have one of the bracelets than that #@!$#@% armband, which always slips or leaves marks on my arm for hours afterward. Something about the shape (or lack thereof...) of my bicep makes them a terrible fit.
As best I can tell, there are two major outlets to get these bracelets from.
This is a much larger company that has more options and caters to all sorts of outdoor enthusiasts. They're affordable, at around $20 per bracelet. It provides basic information that you select. Everything looks neat and slim, and certainly the infrastructure is there to provide quick easy replacements.
These are horseback riding specific. They look a little different from the Road ID bracelets but are still basically the same, though they come in really only one mode. They're more expensive, at $35 per bracelet.
Here's the big advantage to these: they have an ID on the back of the clasp that sends first responders to a website where they can get more complete medical information. I don't necessarily have more medical information to share right now - but it's not out of the question that I would in the future.
Does anyone have one of these bracelets? Which one do you have? Did you debate between them? What are the pros and cons of each?
