This filter does not bring satisfaction to me immediately. We must "tame." No user manual is provided. We must put it in the filter holder for 2 cups. When water (for one cup) has passed, we must raise the lid gently, otherwise it contraption with an English name gets stuck in and detaches suddenly! And as the cover of this filter, poorly designed, is not solidarity, that is left for cleaning kitchen and perhaps clothing. The resulting coffee is good. It is also flawed in that if the handle is curved in contrast to the other handles (lid, filter holder). This is not ergonomic.
