Awesome product
The product is very good and holds a lot of pepper corns. It is also easy to open to add more corns. The price is very reasonable.

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!
