I've owned bi-fold, tri-fold, checkbook wallets, regular money clips, & pocket wallets over the years. Either they become obsolete, bulky, or I just plain hate them. This has been great these last two weeks. Holds 5 cards well and does great with what little cash I keep on hand. It's flat enough that in my work shorts, church pants, or workout shorts that it's barely noticeable.  I do wish the card holder could hold just one more card. My company American Express is one too many but I just place it in the money clip and it stays put. Out of the few "As seen on TV" items I've ever purchased, this is so far the best and most practical.
