Only during the filling of small glasses have to be careful that the funnel is not crowded because of this, as long as it is placed on the glass, the excess content keeps indoors and only when removing the funnel the excess then pours through the glass and the table. So you realize when bottling does not matter if the glass is already completely filled. But that's not the fault of this particular funnel and its design, but rather systemic.
The fact that it is made of stainless steel, a cleaning in the dishwasher is possible. And rust spots by the action of fruit acids he gets surely no. Overall, highly recommended, because of the small, removable outlet connection.
