I previously purchased a pair of these a few years ago and they worked wonderfully. No complaints. Unfortunately, my toddler broke one and I got a new one to replace it. The quality of the new one is not like the old. The height is different now and the lid doesn’t fit quite right. Not a big deal but the lids are no longer interchangeable as before which can be annoying. Also, the glass looks cheaply made and there’s now a seam down the side. (See picture. New on left). Basically, if you are buying one to replace an older model, just save yourself the headache and buy two new ones if it bothers you that there’s different heights and jars.

Pepper in Some Fun

Color: color AA

This thing absolutely crushes and efficiently grinds any pepper just you want it. I was legit amazed the first time I cranked it. You won't regret cranking with me! It hold a great amount of pepper, is incredibly easy to use, and feels like it's a quality build. I am very happy with this.

Good price, good product

Color: color AA

Looking for a replacement of my old battery operated grinder. Decided for a manual one instead, because it is less finicky. Works well, and can adjust the level of fineness. Well made and not too heavy. Can hold a lot of pepper corn.

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.
