I've had this item for over a year now and although I can say that it supports SD cards, there are some serious caveats. The main problem I have is that you can't insert an SD card into an empty slot next to an already full one. You can force it to fit, but it can (like mine) break the ribs on the SD card. You may feel the size is a little different because even one card has too many bends and micro cracks. It's enough for me never to use this thing on a serious shoot as I would add another potential downside. It's not entirely useless as the seal seems to hold, I've dropped mine in salt water with no ill effects on the cards inside. it also appears to be shockproof, but if you shake it, the cards come loose. I usually open the box after work to find the scattered cards. To be honest just buy a branded case, the price difference between it and something like a pelican case is about $4. Given that SD cards are so important, I would choose a different product any day now.
