... this review may not shed light on its most important factor.  I did not buy it for its waterproof characteristic alone.  I wanted something that was very strong, and dust and water resistant.

-  It is very strong.
-  It is almost certainly dust proof.
-  Don't know if it's waterproof, though, because I don't want to test it, because if it isn't waterproof it could cause a problem with the foam padding.

It would protect against moisture, for sure, but I don't know how it would perform if submerged, sorry.  That is why I gave it only 4 stars.

An improvement I would suggest to the manufacturer is to make them stackable by having the pattern on the bottom fit into a pattern on the top of another.  I've bought more than one.)

Also, some of the snaps are extremely tight (need a flat-head screwdriver to get one of them open), and some are a little looser than I thought they would be.

Nonetheless, I am thrilled with them for my purposes, and after looking at alternative brands.
