Query: Mostly Unusable

The review that mentions shaking the beans is correct. It is quite messy as well. All the interlocks can sometimes prevent the operation of it. Removing the top burr to clean it is difficult. The part I don't like is the space that leads from the burr wheels to the storage chamber constantly clogs if you use beans that have any visable oil to them. I like that kind of coffee. If you use mostly light roasted dry beans, it may be OK. I clean the thing well and attempt to grind coffee and it is clogged before I have enough for a single cup brewer! I suppose I could clean it out several times during a grinding, but that is also very messy and is the last thing I want to do in the morning when I want some fresh brewed coffee. It sits on my counter taking up space. I may give it to a charity like Goodwill or just trash it.
