I wanted to wait a considerable amount of time so that I could use it enough to evaluate it. After about 1 year of use, I would rate it… almost excellent, and I will explain below why not excellent.
First of all, I want to comment on the adjacent review of the red Cillio, which is essentially the same as ours, only the color changes; it is black, and I was puzzled by the damage it suffered.
To screw on the cap that presses the fruit, you have to do it very carefully because the turns are very small and numerous (obviously to ensure stability), so you can easily make a mistake and it can "catch" crookedly. Also, if it is not screwed all the way up, it may lack stability and damage may occur. That’s probably why the turns "kicked" and it doesn’t screw on. There is always the possibility that it was defective. However, it is definitely not fake in any case.
Anyway, with a wet cloth, you can clean it after each use without unscrewing it daily, and once or twice a week, you unscrew it for a more thorough cleaning.
For us, it presses 10 to 12 kilograms of citrus fruits per week (over 350 kilograms a year).
During the season when pomegranates start and for as long as they last, it gets crazy. Well, it does it very easily and the result is excellent. Without much fuss, you have juice in a few minutes and with no preparation. Cleaning, as I mentioned above, is very easy. Occasionally, depending on the size of the citrus fruit and the pressure, a few drops of juice may splash out.
Finally, as the instructions state (not in Greek), when it starts to make a little noise when lowering the lever, we put a little machine oil or olive oil (I used olive oil) on a cloth and lubricate the shaft. I did this twice in a year. So, I would say it is a very good kitchen appliance.

So why do I not rate it with 5 stars?
Because of the price. I believe the money they ask for is a lot.
In summary, I think it is an excellent tool, without having an opinion on other cheaper similar designs that may do just as good a job. Time will tell.
If it cost around €100, I would recommend it without hesitation. After all, it is not something you buy often.
