I have a few that are similar that I purchased at Wally World for about the same price. They work well for small amounts of ammo or range supplies, but any long-term storage for my ammo is in GI metal (50 cal. or 30 cal.) cans.
It's been my experience that NOTHING stands up to long term usage like the GI cans. I'd just save my $$ and use it to purchase the GI cans when they're on sale.
They are handy for general storage. If heavily weighted, the seal will let air in when you pick it up by the handle, as the plastic will flex. That's been my experience anyways. Those Bunker Hills look solid though. 50 cal holds more
