Looks nice. Doesn't work!
Color: color AA
This thing is cheap trash. The inner ring keeps popping off into the food. If you don't keep it tight, while peppercorns come out. It's going right in the trash where it belongs!

Works but quality of top doesn’t seem long lasting
Color: color AA
I bought this as a replacement for a grinder that came in a similar set I had that broke. This grinder works alright, but it is not as good quality. I will not be returning the item, but also will not purchase this grinder again.
