Ill add my opinion:
1. oily beans may stick? if you push down on the beans I generally find this works, although i probably only have to do this about once a month.
2. I have never wanted to empty mine - just put in what you need.
3. I adjust finer while running. you can do it with 2 hands - use your little finger on the latch.
4. its a grinder - it grinds!
5. recommended settings are pretty useless. use whatever you need.
I think the rocky is realy good, and I wouldnt regret your purchase.
