I've grown tired of carrying a fat wallet in my back pocket and thought I would give this a try. After about a month I find I am very happy that I made the purchase. This little guy does it all and does it exceptionally. No more sore butt and back after driving for any length of time. In a bonus H.D. Thoreau like manner it made me pare down the junk I was carrying with me. Simplify, simplify! I feel so much lighter I could dance... or go to Walden Pond. Thanks!
