The design is really neat and I like the minimalist aspect and the ability to turn the cards inside out very quickly and easily. The ONLY issue I have is that the spring that holds the card in place has loosened over time. Even with the maximum number of cards in the wallet, a card will still slip out of the wallet if it lands in my pocket upside down or is turned upside down for some reason. The internal spring inside to keep the cards inside was stronger/better quality
