Maybe I have low expectations, but I'm super stoked with these. Definitely some flash rust on each one to varying degrees. A lot of that would probably wipe off with an oily rag. The insides and the seals look as good as any other grade. I opened each one I bought and looked inside first.
I picked up four today and I'm very happy with them - perfect for storing small amounts of ammo in a bunker, basement, truck, etc. Some "hobby calibers" I guess you'd call them, I didn't have enough really to store in .50 cal cans, so I got some of these. then I remembered I wanted .30 cal cans for batteries, too, so I'll have to go back and get some more.
Also got an "Aqua Pod Kit" - same basic thing as a Waterbob - a bladder to line your bathtub and fill with fresh water. I have two bathtubs so now I have one of each. Hopefully I'll never have to review them. It's kind of a catch 22 - I should probably test it, but I don't want a big wet plastic bladder collecting mold.
