I have used the road ID for a couple of years.
I hate having anything on my wrists, ankles etc.
I got the shoe one but rather than put it on my shoe I strapped it to the side of my helmet. Hopefully if I crash they will see it.

An EMT I talked to said wrist or necklace is the best because that is what they are trained to look for. I may have to suck it up an get used to wearing a necklace

I bought a Gray/Black strap - now I wish I had gotten something more visable
