Larger cards fit perfectly in this case and are well protected. I'm having trouble inserting a smaller card and keeping it from moving, but I'll admit it could be me and don't want to push too hard. So my solution was to put a big card on top that you need if you want to use all the slots. I have a lot of empty slots *giggle*. I like the case and it feels really solid. I gave it a 3 just for being waterproof because I WILL NOT try that feature! The case closes securely, and that's probably why it's waterproof. And it is highly doubtful that the case can open on its own. Overall, I'm happy with this purchase.
