Great grinder, consistent, easy, versatile, and Rock(y) solid.
Positive Product Points
Best doserless grinder there is, saving the coffee for the portafilter and not for the rubbish. Good quality grind - producing very consistent particle sizes. The range of gring settings is large giving all you'll ever need from French Press to Turkish. Easy operation - I like the master (for safety) as well as the operation switch (Nice positive feel). It's a sturdy beast and because it's heavy you won't knock it over. Relatively compact and small footprint considering its a very effective grinder.
Negative Product Points
Grounds get caught in the chute from the burrs to the exterior. Could be argued to be slower than optimal.
My wife bought me this machine as a present for passing my PhD last year. I had no idea at the time but she carrried it all the way home. She's no beefcake either! She isn't a Coffeegeek but she's learning.
We had discussed the advantages and disadvantages of the Rocky and Mazzer mini. The deciding factors for us were the price £180 to £320, the size in our rabbit-hutch (The Mazzer's really very tall with the hopper on) and most importantly the doserless design.
The doserless design should be ubiquitous in all consumer grinders so as not to introduce stale grounds and makes it infinitely easier to clean than a doser. With the finger-guard removed, I found a quick suck with a vacuum nozzle does the trick.
I am very happy with the grinding consistency of the Rocky, and my shots have improved no end. Mark Prince's review of the Mazzer mini helped me to choose the Rocky on this count.
I can see that the Rocky will last a good deal of time and can thoroughly recommend it as an espresso and all-round coffee grinder. Changing the grind setting's a doddle - click the wheel around (nice positive action), just run the motor for a few seconds, sweep the burrs, run the motor and you're good to go.
As all Coffeegeeks know - Grind for the shot! This machine helps you to do this remarkably and so earns high marks. Combined with the excellent grind quality and build quality I can highly recommend this grinder to anyone with or without a budget.
According to my wife, Drurys held the doserless version for two weeks for her, while many others, including me!, requested the doserless Rocky - which was out of stock. It seems like supply might be your only niggle and that might just be Rancillio.
Three Month Followup
Going really strong - showing no signs of wear to speak of. Switching grind settings is easy if you're careful to clean out the old, differently sized, grounds. Doserless for the home user is the obvious choice. Cleaning is fairly simple and shows little sign of excess build up of stale grounds. Anyway if you're getting stale grounds, have another coffee! Have one for me too. :-)
