It's not bad for what it is
I got the Rocky with the Silvia combo and used it to grind for espresso, drip, french press and pour overs. I got the model with the doser but in hind sight the one without may have been better for me. Most of the time I dose into a cup not the portafiller. I took the "fork" the portafilter sits on off so could put a cup or a filter for drip under the doser. I find the doser tends to dispense to the side so it's messy if I try dosing right into the portafilter. The doser is nice to have and may break up clumps and it may be a good habit to use one but I don't think it is needed. I usually use a little brush to sweep it clean. This helps keep it clean and when changing from one coffe or grind to the next I don't get mixed doses. Also sometimes I keep the hopper empty and weight what I need then grind it and sweep everything out and re weight to see that I got everything out I put in. Cleaningis easy and the solid brass seems to be a Rancilio Feature. It is best to clean with the hopper is empty other wise you have to turn the entire grinder upside down to empy it. It gets the job done and looks nice and is quick to adjust from one grind to the next. The size is nice if you use about a pound a week.
Everybody sells it so you can shop around for a deal.
Three Month Followup
I've had this for over a year but posted a review late. This grinder has been around a while and reviewed many times. Most people point out what they think is bad with this grinder but I find it fine. If you look at the brass ring and base that support the burrs they are impressive. The heat that grinding produces is pretty amazing and the heavy brass is perfect for this. Not cheaply made. The adjustments are fine. People have writen they would like finer adjustments but the system is fast and easy. Also it is easy to reference quickly from one grind to another. This makes it nice for switching from a grind for a Hario to a chemex with a Kone or espresso. I found if I remove the stop screw I can unscrew the hopper like other grinders to clean it or take the screws out that hold the hopper to the base. For dosing I removed the portafillter holder and a small cup fits under the doser so it is easy to measure doses with a scale. It be nice if it was faster but I have not tried other grinders in its class to compare. That may be based on burr size and motor power. It may be faster than the other grinders it is compared to. In summery it's a great grinder that with a couple of personal tweaks can do it all nicely.
