Exactly as I expected. Perfectly ergonomic in both the filter application and the cup. It is designed so that the coffee extract does not escape outside the cup and falls with such a flow so as not to splatter. The flow hole of the extract is such that the extraction time is appropriate. Neither too fast nor too slow. I am completely satisfied with its functionality. The only thing I fear is that as porcelain, there is a risk of breaking during washing or storage.
