Good quality, easy to use
Color: 2-Speed Rechargeable Set with Base
I absolutely love these grinders. I always thought electric grinders were silly but I’m so glad I bought these. They work great. I like the adjustable grind and the light really helps. They look nice and are well made.

Best electric pepper and salt grinder for a very reasonable price!I
Color: 2-Speed Rechargeable Set with Base
I've spent over $200 on salt and pepper grinders including very pricey manual ones and a name brand electric grinder which was costly and had a weak motor. I bought these expensive grinders thinking I would get a quality product by spending more money. Well, it was a waste so I decided to try this highly rated Circle Joy grinder and, so far, it works incredibly well! The high/low speed works exactly as expected and at high speed, it grinds really fast. The motor is powerful and does not feel like it's going to give up even when grinding salt or pepper at high speed and on the fine setting. It is easy to refill, holds a long charge and just simply works. Buy this. You will not be disappointed... and say goodbye to having to wash your hands everytime you flip a raw piece of meat or chicken to salt and pepper when using a two hand manual grinder.

Works well.
Color: 2-Speed Rechargeable Set with Base
Close to 5 stars. Only minor complaint is somewhat shorter battery life then expected. But since it is rechargeable, not a big deal. Like the adjustable grinder and the clear container so you can see how much it has.

Great salt and pepper set!
Color: 2-Speed Rechargeable Set with Base
Great salt and pepper set! I love that it has a light that makes it easier to see how much is coming out. Very easy to use, easy to fill, nice selection of grind sizes. It is also nice that it has a base to hold it because there is a very small amount of salt that comes off the bottom so it keeps it from going on the counter while not in use - it's not leaking, just leftover residue from the grind you have just finished.
