Should be MORE than adequate for any reasonable person.
Positive Product Points
Compared to the Bodum Antigua, that I had, it is QUIET! It has a small footprint on the counter top too. It LOOKS GOOD!
Negative Product Points
None known. Well, one...but it‘s almost not worth mentioning. The Bodum had little icons at the "normal" grinding settings for whatever you wanted the machine to do. The Solis has markings only. You have to experiment a few times to find the setting that suits your taste. No big deal.
I see other people say that it is noisy, and others "make sure it grinds fine for your machine"...I don‘t see either of these comments being a reality. It is reasonably quiet. For God‘s sake...it‘s GRINDING BEANS!!! It certainly grinds "fine"...in fact, the finest setting is too fine a grind. It ain‘t cheap...$125 from wholelattelove, but I think it‘s worth it.
