Great for Moka Pot, French Press, Drip, Vac Pot - pretty much everything except espresso. Consistent grinds, easier than Zassenhaus, less static than melitta, and slow enough to not produce much heat. This yields an all-around better cup due to even extraction of all grounds.
Negative Product Points
I hate the timer. If I were you, I'd buy the "Classic" from Costco. It's about 30 dollars cheaper and more effective. I don't use this grinder for espresso, but I wouldn't recommend it - not enough adjustability.
Detailed Commentary
I bought this grinder to replace my Zassenhaus for using as my drip/french press/vac pot/moka pot grinder. The zassenhaus was a great grinder, I was just getting tired of using it once or twice a day.
The first thing I found out when I got this grinder - I'd been grinding way too coarse for EVERYTHING. With the Zassenhaus, the setting I used for moka pot is the same as the setting that the Maestro uses for drip.
This machine is so much faster than my Zassenhaus - 30 seconds compared to 3 minutes. This saves tons of time in the morning.
Much more consistent grinds than my Zassenhaus - finer grind yields a more consistent grind, so my french press coffee has a lot less sediment. I now see why people like it so much.
Really, this grinder is a much better buy, in my opinion, than a Zassenhaus. It's not significantly more expensive (about 10-30 dollars) and makes the whole process much easier and faster.
Buying Experience
Great - I had a problem with something else I ordered with this machine and it was fixed within 3 days.
