I like these. They are also the only ones I could find with a gasket on Amazon, so didn't have anything to compare to. They are not heavy duty. The aluminum is light gauge which is perfectly fine for this size. (you're not filling it with tools, etc) My only issue is the clasp is a bit lightweight. I bent one in the first 5 minutes. Not a problem, just bent it back and it works. But again, light duty only. I don't mind the light gauge construction, but I really wish the clasps were heavier duty with a positive, foldover, locking hinge. Still, for just keeping stuff dry and safe from crushing when packed, these work fine.Note: I have not tested the seal beyond confirming it holds against incident moisture (rain, splashes, etc). The gasket is light enough that, combined with the weak clasp, I would not trust this tin to be submerged at all.
