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.

Good Buy
I used for the first time today. I’m very pleased at how it functioned.
Ease of use is great and it looks nice as well.
It’s larger than I expected and I’m very pleased with that, because it means I don’t have to refill the bottle so often. I only purchased to use for the peppercorn not for salt. I’ll buy another one for the Himalayan salt.
I highly recommend.
