It is a fun to use and the kids love it. It does the job reasonably fast and the results are good. Very low annoyance factor and nice hands on approach. It can be used for espresso. Mobile I can take it everywhere and is rugged.
Negative Product Points
Not as good for espresso as a dedicated a grinder. Difficult to clean. Finish quality and noise don't live up to my expectations.
This is my first coffee mill and I like it very much. I have used it and got great coffee with french press, vac pot and espresso machine. Grinding driven by yourself is a part of the coffee celebration. My kids (3 & 5 years old) argue who is allowed to grind my coffee. It is definitely more fun than using the electric grinder.
And now the details: Speed is sufficient. A load for the vacpot (8 cup silex with stove) is finished in the time the water needs to heat before adding the top globe. I can walk around while grinding and talk to others. In a quiet environment there is some squealing from the bearings. Grind results are good and I could use it for espresso but it is not as good as my innova. Most difficult for espresso is the proper adjustment and my special unit wasn't fully centered. The burrs start touching not evenly but at a certain angle. It is dfficult to clean. The hopper is closed and even a brush is difficult to fiddle through the small opening. Also the grinds falling next to the drawer are difficult to get out.
I had bad luck on this one. The pile of orders at Sweet Marias was to big so they forgot to include it in my box. So I had a roaster, green beans but nothing to grind with. The problem got resolved quickly and with personal touch from Tom & Maria. So it was still a pleasing experience.
