Defective coarseness adjuster
Color: Tall Set - Black White
These salt and pepper shakers are ok. According to the description of the product, you should be able to adjust the coarseness of the salt and pepper added to them, but that was not my case. The coarseness adjuster on the set I received is set to one position and there is no way of changing it. The grinders work well, but if you are looking to adjust the coarseness of your salt and/or pepper look for another grinder set.

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.
