I am very happy with my zassenhaus grinders at home and it has been my one of the things that I collect.
These grinders are very effective so I love these grinders. I use it almost everyday and even though it is a manual grinder and you might think that it is not that effective, I must say that this is one of the most effective grinders I have ever tried.
It grinds uniformly and the coffee comes out really great and it squeezes out all the oils in the beans which makes your coffee taste really great.
I would recommend this grinder to all coffee enthusiasts.
