It is an amazing grinder, relatively quiet (and without unpleasant noise). It grinds quickly and the ground beans come out quite separated without clumping.
Flat blades 55mm with a profile that focuses more on body than clarity and distinct notes. Ideally suited for medium-medium dark coffees, without being prohibitive for lighter roasts as well. It is a quite capable grinder, able to grind very very fine easily and clog the extraction.
It is sturdy in construction and, in my opinion, beautiful.
For this price for purchasing a non-manual grinder from Greece, Eureka is a guarantee. It also has representation, so whatever the consumer needs, they can find solutions (although I have never contacted their technician, I was very satisfied with their service).

The reasons I take away a star, to be objective:

- Dial Knob:
The grind adjustment is unacceptable with the dial they have (on all Eureka grinders). It is not convenient at all for small adjustments (but neither for large ones, for people who drink both espresso and filter and frequently change grind). You also can't remember where it was and how much you will change it exactly.
In the newer Mignon Zero (65mm) they have put a larger and more convenient dial, and they should gradually integrate it into all their models.
However, the issue can be easily corrected. There are after-market solutions if the grinder meets your other requirements. Now Eureka also sells the king size dial (which is what the 65mm Zero has) and it fits all Mignon models.

- Quality Control:
Although Eureka is well-known and reliable, the quality control (at least on these grinders) is not sufficient. Specifically, the burrs' alignment is not always correct, resulting in needing correction with different screws on the top side (rotation of the upper part). If you don't have a similar grinder, it's hard to describe it here. Those who have the same and have issues, know that you are not crazy.
The grind I was getting at 0 was like beach sand (0 is not always correct as an indication, as it may say it is at position 0 but does not correspond with the actual position of the blades*). It wouldn't go lower as it sounded like the blades were touching.
As soon as I opened it, I changed the position (horizontal rotation) of the upper part of the blades and now they "fit" better, resulting in me being able to get such a fine grind that it was like butter (and of course nothing ran through the machine, I had to grind much coarser for it to come out).

Some tips for those who decide to buy it:
1. The bellows need more "punch" to release the retention.
2. Although it has bellows, the retention is indeed little but not zero. On the first coffee of the day, I sacrifice a few beans to make the cycle for those that remained from the previous day.
3. As I mentioned, the 0 on the grind indication does not necessarily correspond to the finest grind. You need to find the actual zero point of the blades to work it better (there are videos).
4. As you use it, you will see improvement in the quality of the grind. When it is new, the blades are quite sharp resulting in the cuts of the beans having many gradations and there being quite a bit of bean dust (much finer particles than what you have set it to grind). And obviously, it affects the extraction.
You will see how it is referred to as seasoning of the grinders, but in reality, it is done to reduce their sharpness, and over time the grind becomes much more uniform (i.e., to avoid large variations in particle sizes as much as possible).
It doesn't mean that the coffee won't be drinkable at first. But after 2-3 kilograms of coffee, you will start to see improvement.
This applies to (almost?) all grinders, so it is more general information.

The conclusion is that for this money, I probably wouldn't choose anything else. I am satisfied despite the issues I mentioned (which surely some will exist in more expensive categories of grinders).
I wholeheartedly recommend this particular grinder (and probably the entire Mignon series as they are similar in various characteristics).

However, what worked for me doesn't mean it will leave anyone satisfied.
Decide which functions/features are important to you, what result you want to achieve in the cup, which disadvantages would prevent you from choosing it, what your workflow is when making coffee, so you can make the right choice.

I have had the grinder for a week now and I am trying my best to learn how to use it. From the first coffee, I noticed a huge difference compared to before when I used to buy 250g from coffee shops and it would stay in the box for 10-12 days, resulting in losing all its flavor and aroma.

I will start with the negatives that are immediately apparent:

• The instructions do not have Greek language. They only have Italian (obviously since it is manufactured in Italy), English, German, French, and Spanish. I had to watch 15-20 videos before purchasing it to see what to expect, and just as many to understand how to adjust it - which brings me to the second negative:
• The adjustment wheel is confusing. It has simple numbers from 0 to 9 and it spins. If you don't know what you're doing, you might accidentally break it or at best, you will need to throw away several coffees that won't be drinkable at the beginning. It requires a lot of effort, much more than I expected. These specific videos helped me dial it in (a 15-minute process and 1-2 coffees in the trash until you get it right):

• Additionally, the instructions state that the grinder should operate at -5°C - +30°C. This automatically excludes Greece as a country of use since we have temperatures above 30°C throughout the summer, usually 35°C.

Overall, the instructions are the only weak part as it seems that not much effort was put into creating them. The installation steps are two pages behind the words that describe the steps, so you are constantly flipping back and forth for about ten minutes to make sure everything is correct and you haven't forgotten anything.

Other than that, we are talking about a sturdy construction, high quality, with almost no plastic except for the pump cap on the top, which, although plastic, seems to be of good quality and just requires a little attention so it doesn't fall from a great height.

I will regularly come back to update my evaluation as we are talking about a professional machine that has a lot to offer, especially for this price.
