    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.

    Very nice set of salt and pepper grinders. They work perfectly. A charge lasts a long time on them. Very easy to use them without having to use a lot of pressure on the buttons. I love the looks, very stylish. You won't regret buying these grinders.

    Great salt and pepper grinders!
    Size: 2 Pack (95ml), Color: Black - Storage Base, Size: 2 Pack (95ml), Color: Black - Storage Base
    These salt and pepper grinders are great! They are rechargeable and grind at the push of a button. So easy!! They look expensive and hold a lot of salt and peppercorns! I have to admit that I wasn't expecting much from these plastic grinders but I love them! The design is perfect, functionality is great and I don't even notice they are plastic material! If you haven't tried electric grinders, try these!
