It's awesome! I have quite a few cards that I carry around, ranging from credit/debit cards, gift cards, driver's license, health insurance card, etc., and this thing holds them all. As others have mentioned, it starts out EXTREMELY stressful and removing cards can be difficult, but it loosens up a bit after collapsing a bit. It's so ridiculously light and thin that I often forget it's in my pocket and rummage through it in a panic, thinking I've forgotten my wallet somewhere. If you want to lose weight and clean up your wallet, then this is what you need.
