Not for the weak...
Color: 1 pk
A bit tough to use. My blend has green peppercorns in it. The mill does dispense a finely ground powder but it takes some significant wrist action. I don't love this item which I find VERY "manual" though quieter than any motorized version. I wouldn't buy it again.

I loved it! The grinders look very elegant and work perfectly. The size is great, they’re easy to use, and the grinding is smooth. They also feel sturdy and good quality. Definitely recommend!

Nice grinders for the price
Model: 2 Pack Salt and Pepper Grinder
The grinders are working fine, though I have only used them for a couple of days. Their size is a little smaller than I would like for in kitchen cooking, but I got them knowing they will work better in a planned move with a smaller kitchen. Good size for a table. I'm happy with the clean, simple appearance and the quality so far. Just ordered a second set for white and mixed color peppercorns and will donate the sort of hodge podge assortment of grinders I currently use.

Love them
Model: 2 Pack Salt and Pepper Grinder
Love those. Good quality material and work very nicely. I like that I could set the size of the ground salt and pepper by myself, this was very useful.
