I love the fact that I don't have to cover my cards with aluminum foil any more.  All my credit cards fit in the slots which are large enough that I can double them up.  I wish it did have another slot side but my non-critical cards fit in the outside side pocket.  With the little wrist strap, it's all I need to take into the store.  The craftsmanship is good and I have found no flaws.  I would buy this again.
