Bests & Worsts Reviews from Amazon

How can I put zero star. Seriosly bad. I used for a butter flavor popcorn salt. And after two years of normal use, I opened to refill it then I’m shocked. It was never touched by water since I rince it and dry it out before the first use, but it rusted everywhere. And some small black (rusty) things are mixed with the salt. I doubt we all family ate rust powder for two years. I feel I have to sue the seller and Amazon. This product should be banned to sell. Do not buy this.
