Love the product. It is much better than I thought it would be.
The magnet does not affect the credit cards. I did a little research to see if magnets can break credit cards- they are not supposed to. I carry 3 cards in this wallet and all cards work fine. The magnet holds money well.
This is much better than other money clips I have used - especially better than metal clips. Much easier to get money out without fear of dropping everything.

Great product.
