The plastic is dense and tough with no flex whatsoever, so protection is quite good. The waterproofing grommet moves slightly in the case but I can't confirm whether this affects the seal, I'd rather not test that. The SD cards fit in the dense foam very tightly, which is good, but it does take a little bit of fumbling to actually put them in in the first place. The outer clip is just hard plastic also, which might wear over time - hard to tell just yet. Overall, a decent product to organize my cards and gives me a bit of peace of mind that they are kept safe and secure.
