This card holder is great. I use it as a wallet since I don't carry cash on me. It fits seven plastic cards and it is made with superior material. I have had mine for about two years and it is still looking great. I have used it every single day since I purchased it. Many people complain about the cheap material. It is most definitely not cheap, but like any other wallet, it deteriorates with time. Even leather wallets do. However, I definitely don't recommend it to be carried in the back pocket since you will bend the metal. And as far as it demagnetizing your cards, that is true, just don't let them come with direct contact to the magnetic strips. It takes a bit of time to get the hang of it, but once you know how to, then it won't bug you.
