I wanted to eliminate the bulk that I have been carrying around in my back pocket.  So I got this not really knowing if I could make it work.  It is even thinner than I expected.  So when it got here I cleaned out my Cabela's leather wallet, taking out the cards that I didn't need to be carrying around with me every day.  It is amazingly small and thin, I'll never go back to a fat wallet!
Two negatives. 1. It is so thin that sometimes I panic for a few seconds because I don't think it's there.  2. I'm afraid that I'll forget to take it out of my jeans and it will get washed.
