I've tried many card holders and they all have the same problems. This one is well built, closes tightly and feels very waterproof. Unfortunately I haven't read how much space there is for each card type so just having 4 SD slots wouldn't work for me as I have more cards they could easily do 4 more SD cards on top of it. Micro SD cards. Along with the very few SD slots, like all other card holders I've used, the micro slots are ALMOST IMPOSSIBLE TO REMOVE. If you don't have long nails, you can't remove Micro SD card without tools or with another card. Unfortunately, for these reasons, this product is rubbish for me and really useless.
