Just received this item, which was a great value at $7.00.  I think it will be fine as long as I don't carry a lot of cash;  the magnet isn't very strong, and while it will hold eight bills somewhat snugly, I doubt that much more than that will be "doable" until the magnet fails to secure the cash.

The ID window in front is handy for one's driver's license or other identification, and the card slots in back hold three cards securely.

I plan to use this as a travel wallet, where I only carry my license, one credit and one debit card, and health insurance card.  I doubt it will work for everyday use.

Not bad for the price, but I don't see it as a replacement for one's "real" wallet.  Either that or I need to simplify my life as in not having so many cards;)
