I know I'm resurrecting an old thread (I'm new here and going through the archives), but what I love best about this wallet is being able to pull my debit card out without having to open my wallet. I've always carried an accordian style and was used to the vast amount of space and security of the zipper, but it took less than a day for me to get used to the strap. I don't think I'd ever go back now; the accordian style just takes too much space.
If you put your most used card in the slot near the end of the wallet, you can pull it out without ever having to take the wallet out of your purse.
