Review on Minimalist Aluminum Organizers for Men's Accessories: Automatic Wallets, Card Cases & Money Organizers by Lungogo by Kevin Barbon

The cardholder has a major problem that I only discovered after a few weeks of use. The cards aren't held firmly in the slot, so I've found several times that when I take the card holder out of my pocket and the slot is facing down, my cards land on the floor! I wrapped it with rubber band but of course that defeats the purpose.
