Great grind, niche product, works very well...you have to work for it.
Positive Product Points
The absolute least expensive way to get a good espresso grind.
Negative Product Points
You have to work for it, and the settings are sort of a guess. You can only really set the grind based on the last grind. They do not work well for oily dark roasts.
Detailed Commentary
Very high quality parts and solidly build. Will last a very long time. While this is clearly a niche product, it has a really nice feel and will create a very high quality consistent grind.
More expensive machines will have 1) a motor 2) very accurate grind settings...the grind will not be better.
So for the home, (and not entertaining by the way at home, you will kill yourself spinning this thing) there is no better value out there
While dark roasts are oily and will clog up, a loose is setting...I think dark roasting kills good coffee anyway it is not really a problem for me.
I use this at work and have a Gaggia Evolution sitting next to it...the manual function actually keeps me from downing shot after shot. Which is good.
Note my produces faster with a even slow turn, spinning too fast seems to be counter productive.
Buying Experience
Local shop, great experience. Had good insight into using the machine
