Things I love is everything about he wallet when it comes to holding cards. The slide mechanism still works amazing and have never had any issues. This is designed to be a front pocket wallet.
Thing that need work, anytime you need to use cash. Using cash is a pain with this wallet. Dollar bills are too long so they have this weird 's' shape to them, making getting bills out of the wallet difficult and untidy. The leather itself is soft, and feels nice but is susceptible to scratches from keys. The leather is 'glued' to plastic which is glued to the aluminum card holder. I've had this wallet for about a year and still like it but the cash part sometimes drives me crazy.

If you are a heavy card user you will surely love this wallet, but I'd recommend considering skipping the leather part of it and just getting it for the card slide.
