Excellent so far in the first few weeks. Several Suggestions: increase the thickness capacity of the slide out section by 1 or 2 more cards. Provide a viewable window on the interior facing slot for driver's license/ID card. Clarify the purported 14 cards capacity requires a add-on unit. Provide another interior slot on the rear inside of the fixed portion and opposite the existing slots of the wallet's flap. Make this accessible w/o having to move the elastic band. Such additional slot would increase the wallet's overall capacity and provide another method to accommodate thin paper printed cards, such as Medicare, Soc Security, etc. which do not work well in the mechanism portion. Currently, such thin paper cards, plus a few business cards, almost completely fill the exiting two inner slots.
