Incredible quality!!!
Color: Black/Black
We have had these for a little over three months and so far they are still working fantastically. We are amazed at the quality for the price. It makes grinding fresh salt and pepper so easy! Perfect for cooking and topping food.

Works well, just wish it was rechargeable
Color: Stainless Steel
These grinders work pretty well and are really convenient to use with one hand while cooking. The adjustable coarseness is nice and the LED light actually helps more than I expected. They seem well made and hold a good amount, just wish they were rechargeable instead of using batteries. Still happy with them overall.

More than a daily grind
Color: Purple
We are very happy so far, working very well. The grind is even and easy to adjust with a simple turn of the screw on the base of the grinder. The automatic light is a nice feature, especially as I am 66 and my eyes are not what they used to be. Once I turned the on button to face front, I'm no longer triggering a grind just by picking these up. (our last grinders trigger was on the top of the unit}. They feel well constructed and are easy to fill. My wife absolutely loves the color (purple). will update this in a couple months for durability, but for the price so far (1 month) 5 stars

Electric grinders
Color: Black/Black
Easy to refill. We use pink Himalayan salt and the grinder does well. It seems to struggle a bit with the peppercorns bit still gets the job done. The light is nice. We have enjoyed the ease of use. It also looks nice on the counter. The holder is great as it catches any fine debris after use. I purchased this one as it uses actual batteries and not something else I have to charge. They have been used daily for 2 months and have not needed to change the batteries yet.
