    Low price, low quality.
    Don't be fooled by the low price. All of these grinders are not the same. It would not function and I sent it back. Spend the money and buy something better that you know will work.

    Not just for salt and pepper
    I've had one for years to grind Himalayan salt, and bought a second to grind Trader Joe's Soffritto seasoning blend. Perfect!

    It was inexpensive
    It holds a lot of pepper but honestly it doesn't grind to a very fine setting. It HAS settings but I feel like they're all the same, pretty coarse. Overall however it works.

    Good value, good product
    This grinder works great. You can choose between very fine ground pepper to course ground. Most grinders tend to be difficult to get down to the fine grind after some use, but this one holds true.
