    I've had this specific brand for my Samsung phones since I like to carry my cards and my phone with me always. This specific case, I've used my phone hard-core and have dropped it at least 50 times. It finally cracked (see first pic) when I dropped it on concrete on the bottom corner. But, again, I've dropped this phone plenty of times. I'll probably buy another one soon but for now super glue is holding it together... til I drop it again. It's probably best to store 2 cards (imo) but you can add 3 if you want to. And my only "issue" is that dust and dirt still get inside on my phone...
