I've had the gunmetal one with the cash strap for about a year. It's a rugged little thing and I've been happy with it. It really made me rethink what I carry in my wallet. I'm down to my driver's license, one credit card, my insurance card and one $20 bill that rarely leaves the strap because I hardly ever use cash anymore. It's held up well. No problems with the strap or the bills falling out. It's pretty scratched up, but thats to be expected as I keep it in my front pocket with my keys. Thumbs up overall.
