What she /|\ said!

I've got an Illuminite hat, arm warmers and a jacket. The hat I bought intentionally, the rest were from a gear swap and clearance. I wear them when I walk my dog. I figure any extra help is good. But, they really don't work very well. They do something, but you really have to be right up on it to see the reflectiveness. So, if someone is giving away arm-warmers and you need arm-warmers and they happen to have Illuminite, buy them. I think that the 3M reflective stuff is much more effective.
