Bought these for my mother in law who has some slight mobility issues so turning a salt/pepper grinder wasn’t easy for her anymore! These are so easy to use you literally just click a button. I also love that the battery is rechargeable so you don’t need to buy any extra batteries or replace them. It’s very sleek and modern looking and easy to clean. You can also adjust the size of the grinds to your liking. Definitely worth getting and great quality!

No More Manual Twisting of the Grinders!

Color: 2-Speed Silver, Size: Rechargeable

This is my first time trying this type of product and initially I was a bit skeptical they would be helpful but after using for some time, I find I really like them! I love freshly cracked pepper and salt, but the twisting of the manual grinders was becoming tiresome. This set holds a good amount of peppercorns and the batteries seem to last long. Very easy to use if you learn to pick up without touching the buttons. These do the trick! Great product!
