An excellent home grinder. Tighter settings and a changable hopper would make it a great grinder.
Positive Product Points
Built like a truck. Nice size, fits under my kitchen cabinet. Grind settings are easily changed.
Negative Product Points
No provision to change beans in the hopper. Grind settings are not close enough for espresso. Bolt on tamper.
Detailed Commentary
This is my first burr grinder. I do like this machine very much. I especially like its size since it fits nicely under my kitchen cabinet. Some of the commercial grinders listed on Ebay were very intriguing but I just could not imagine one of those behemoths sitting in my kitchen.
Construction and materials appear to be first rate. Well all except for that plastic tamper thing that was bolted to the front of the doser. More about that later. The Moka 90 has many grind settings. I grind for espresso and usually use just two settings. I would have preferred the Moka to have quarter steps instead of just half step settings or a variable option.
You would think that using a doser would waste alot of coffee. My way around that is when grinding remove the doser lid, fill a section, advance and fill the next, drop them into the portafilter. The sections are ajustable and once set should give consistent doses. The lid does come in handy in the morning when I brush out the doser and drop the stale coffee onto the lid and dump it.
I would use the bolt on plastic tamper as a handle to pull and push the Moka 90 on the counter. That was the only thing I found it to be good for. The tamper was undersized and had a lumpy tamping surface. I finally removed it (one bolt). The Moka now looks so much better and maneuvering the portafilter in place is a breeze. I do have two holes showing on the doser but it doesn't bother me.
Unlike some of the other reviewers, I can not set the grind once and let it ride. I fluctuate on two settings. A setting may be good for days or just for that morning. Once set the resulting coffee is gratifing. Generally speaking, producing a good cup of espresso is always a challenge. I feel the Moka 90 solves the grinding aspect to making superior espresso.
Buying Experience
I bought it slightly used, a customer 30 day return. Did not come with instructions.
