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.

You have to adjust them to how course you want your salt and pepper and they are not electric mills
Color: Clear Glass, Size: 2pk, Color: Clear Glass, Size: 2pk
Comes in a set and nicely priced! Seem to be of good quality and they work well. These aren’t battery operated and you control the amount and courseness of the salt and pepper yourself. They look great in any kitchen and they are refillable, which I really like! They have a good ergonomic design to them so they’re easy to handle and operate. The speed of the grinding depends on how you operate it. I really like these and highly recommend them! Great value! 👍
