excellent consistant grind. improved my shots greatly
Negative Product Points
a little ugly. long grind chute collects a few grams of old coffee.
Detailed Commentary
Right off, I teflon taped the upper burr carrier threads to be sure there'd be no slop as many have reported in the past. It doesn't hurt to do this and teflon tape is very cheap and easy to find.
The grinder is easy to use and is rather quiet. I have only had the beans stop once, but they were large beans and everything was corrected by a little slap on the side.
The grind is very consistant and my espresso shots have never been better. I grinded around 20 for drip and it was some of the best drip coffee I have ever had. My zero point is at zero (burrs just begin to touch) and I am grinding at 6 and 7 for espresso. 7 for fresh beans and 6 for beans 2 or more weeks old.
You don't want to go taking this apart too often, so you'll need a long grinder brush. Always grind a few grams of beans to push out the old stuff, dump it, and grind again for your shots/coffee. You'll only be wasting a tbsp worth of beans doing this and you'd have to do this on just about any grinder if you wanted to force the old grinds through first.
I modified my dosing spout (plastic blue nose) to shorten it so that I could pull out the old grounds in the chute with a brush without removing it. I used a small hack-saw and a small metal file to smooth it out after chopping about an inch or so off the bottom of the spout. The grinds still fall down into my PF if I place it on the metal holder thing, but I usually catch the grinds in a cup and then dose with a measuring spoon.
Buying Experience
home-espresso. I bought and they delivered.
Three Month Followup
Still works, still all I need.
One Year Followup
I love this thing. It's heavy and solid and the burrs don't need changing yet. It out-lived my gaggia machine. Honestly, there's no need to buy a more expensive grinder than this one. I can't imagine what edge you gain from a Macap or a Mazzer. If the burrs are straight and sharp then the grinds will be consistant. Maybe only a high end conical grinder would have an edge over the Rocky.
