It was just what I needed, no electronics.
Easy to fill and change flake sizes. Then just twist and go.

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.
