Lid on one did not work/grind salt or pepper
I received 2 of these products . One is good. The other lid was not good to grind. I had to purchase from a different seller and take the lid off that one to exchange for the lid that would not grind. Nothing would come out no matter how much I tried adjusting the lid. So I was actually out of money for having to reorder another salt/pepper grinder. The one that worked I give 5 stars the one that didn’t I wish I could get a refund on but it’s probably too late to receive a refund. I didn’t try it out until it was too late for a refund.
