I've had this for over 6 months now and it's a really solid wallet. It's a bit thick though, I don't usually carry a wallet in my back pocket, and sometimes I leave it in my jacket pocket or in my front pocket. There's enough space to store up to a dozen cards, as well as a driver's license and a few bucks. The key ring didn't break, and I have a small carabiner to easily remove half a dozen keys. The inside pocket is handy for a few coins, a USB stick or a condom. Although a bit bulky, you're unlikely to lose this wallet, especially with keys attached to it.
