I love the Rancilio Rocky. It's performed very well and I love the consistent grind. My wife thinks I'm crazy but it looks great on the counter.
Positive Product Points
Simple to set up and use. Simple to adjust the grind. The holder holds the portafilter nicely plus I can slip a glass custard dish into the holder when I'm grinding a course grind for the drip coffee maker. I like the doserless because I'm able to grind just the right amount for the portafilter.
Negative Product Points
Only thing I can think of is when I press the button to change the grind setting, it is often the cylinder is stiff to turn.
I bought the Rocky because I was struggling with getting a consistent pull. My wife has a cheapy grinder for her drip coffee, and while it's fine for that, it didn't grind fine enough for Miss Silvia. I buy my beans from a local coffee shop and I was having them grind it for me using their professional grinder. Geez, each time I had them grind the beans, the grind was different. Sometimes it was too fine, like talcum powder, other times it was too course, so my tamp was all over the place. I finally decided to buy the Rocky based on my good experience with my Rancilio Silvia plus the great reviews here. I am very very pleased with Rocky's performance. Using the plastic spoon supplied with the Rocky, I spoon in two spoonfuls of beans and then grind it. I never fill the hopper with more than what I'm grinding at the moment. That way my grind is always as fresh as possible. I read on here where folks were trying to coax the last bits of coffee out of the hopper using various techniques like the clapper lid thing. IF I happen to want to get the last bit out, I just life the lid and flop it back in place a couple of times and it pushes the last bit of grind out.
After 6 months I can highly recommend it, and I would definately buy the Rocky again
So-so. I bought it from the Kitchen Window in Minneapolis. Great store, great buying experience because they have several grinders set up for you to try.
The so-so part comes from a big mistake I made. For some reason I was confused about adjusting the grinder so I called the store, talked to a sales guy, and he told me to keep the adjust button pressed when turning on the grinder. He said something about whole beans getting stuck in there. So I did it. Geez, the canister spun and slammed into one end. Then I re-read the manual where is explicitly says DON'T DO THAT. So now the adjustment is often stiff and not smooth as it originally was. When I was in the Kitchen Window a couple months later to buy some beans, I talked to that same guy and just out of curiosity I asked him the same question. He gave me the exact same answer about holding that adjustment button down while spinning up the grinder. I didn't say anything but I know I screwed up my Rocky by following his instructions. So do not ever press the adjustment button while the grinder is spinning.
