Good quality and great value
Size: 2 Count (Pack of 1)
Willow & Everett Salt and Pepper Grinder Set - Stainless Steel Manual Mills I bought this set because my smaller pepper grinder broke. This set is very similar in style, though larger. I really like it! The larger size is easier to handle and can store more pepper and salt inside it, meaning it needs less frequent refills. The adjustable grinder mechanisms work very well. The lids are easy to take on and off. The caddy is a little flimsy, but that wasn't why I bought the set. If you are swayed by the caddy, then you might be disappointed if it receives heavy use (like a family dinner table). But the mills and grinders themselves are good quality and a great bargain.

Simplicity wins here
Size: 2 Count (Pack of 1), Size: 2 Count (Pack of 1)
These S/P grinders are simple but I love it. I've purchased several grinders over the years. Some powered, a set using levers to grind, other manual twisters — each with cute features — that all had flaws with filling ease or the powered versions just quit working. This set is so easy to fill, adjust, and use, look, and feel great in hand, and don't break the bank with gimmicks. This set is form and function at its best. UPDATE: So I purchased this set in Nov of 2024. As you can see, it was love. Of late, the grinders have become problematic…especially the salt grinder. The salt grinder got to where even adjust the grind size because it took all I could do to even get the adjustment screw cap to screw on. Salt was getting trapped so I disassembled the grinder cap and cleaned it over and over. With each use, the grinder got more loose. Tonight, it finally gave up. No. These grinders aren’t extremely expensive but, from the reviews and ratings, I’m highly surprised and disappointed.

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.
