Bought to replace a similar Sandisk case. They hold the cards. Maybe it's because it's new, but at least you know that cards (CF/SD) won't accidentally fall out if you forget to close the case or don't close it properly. Speaking of that clasp, it's tight. My concern is that it will wear out over time from friction and constant opening/closing, but no problems after a month of use. Pros: Holds 4 CF + 4 SD + multiple microSD cards, more than enough for me. Hold tight. Waterproof, transparent means you can see what's what. Cons: A little too tight, a little chunky (curved, not flat).
