Commercial quality Big burrs Nice, consistent grinds Great for espresso
Negative Product Points
It has stepped adjustment, and the adjustment collar jumps a little bit when you first turn on the grinder (causing a slight change in grind) It's huge It has a doser, which is unnecessary for home use The attached tamper is useless and only gets in the way
This is an excellent grinder. If you're serious about your espresso, and find a deal on one of these, go for it. I upgraded to this from a Kitchenaid Proline coffee grinder. The Kitchenaid was a nice grinder and looked good in my kitchen, but it didn't make anywhere near the quality of espresso that this machine makes.
I used the Rossi RR45 without a hopper. I would pour the beans straight into the throat of the adjustment collar and place something flat over it to keep the beans inside, or just cover it with my hand. Even without the hopper, it is almost to the bottom of the kitchen cabinets. The grind from this machine is consistent and perfect for making espresso. It could easily be adjusted to make drip and french press coffees. When I bought mine, it came without a doser lid. You need a doser lid. If someone is selling one without a lid, factor in an additional cost of $10 plus $8 shipping to get that from cafe parts.
I got mine on ebay. Not much to say. Generic ebay buying experience.
