Great Value!
Color: Tall Set - Black White
Better than anticipated. These are sturdy and work very well. They came with a little funnel to fill, but easy enough without it. They are attractive, I keep on top my stove as I have room. Grind well.

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.

Works good but have only tried it on fine setting.
Works good but should have an overall cap as seasoning gathers around the inside.
