Great product! So far I have purchased six sets… one for me and five others for gifts. And I only give gifts that are helpful. I like that the grinders are adjustable. I charged them when I think they need it. They have never stopped where I had to charge either of them. I feel so spoiled. Wish everyone could have these. I are very dependable. I’m sure I will be buying more in the future. Thank you for making a wonderful product. I, as well as others, are enjoying them.

Good quality.

Love these. Charge quickly. Love the red light while charging that changes to white when it is full. Love the rack and brush for cleaning that comes with it. Works as it should.
