It's OK but doesn't fit my lifestyle. I regularly carry (and, yes, I've gone through my regulars multiple times to get it it down to my current carry) more cards than this comfortably hold. I've also decided that I really don't like having to fold my money into thirds or fourths. It takes way too much fooling around to get the appropriate bills out and add new bills.
AZJerryTry the version 1. You just need to fold them in half. It's actually very easy to select the exact bill you want from the middle and pull it out without disturbing the others.
