Review on Neewer Black Memory Card Storage Holder - Waterproof, Anti-Shock with 14 Slots for Micro SD, TF, CF, SD and XD Cards by Aaron Leburu

The first thing that struck me upon unpacking was the weight. That is hard! lol seems to seal well, although I haven't actually submerged it to see if it's leaking. In any case, I will not use it near water. I made a start because it's a bit difficult to insert the Micro SD cards correctly. The molded rubber inlays on older cards have small "bumps" along one edge of each card. Insert that edge of the card first or the card won't snap underneath to "lock" it. Also, there is some free space there depending on what cards you want to use it with. I ended up removing one of the rubber inserts to make room for my USB card reader, which fits perfectly, almost perfectly! The inserts are divided into 4 pieces, two in each half of the case, and are pressed in by a pair of small notches that line up with the tabs on the plastic to hold them in place. Nice touch, allows more settings, like removing one for my card reader. :)
