The material quality is ok.
Negative point: I use the funnel to fill water bottles, as the funnel sits on the bottle opening, there isn't enough gap so the water cannot flow freely down, so I would have to stop to lift up the funnel to allow air in between for the water to go down, or create a gap by placing a spoon upside down next to the funnel at the bottle opening. That is annoying.

Χωνί Φ15 από ανοξείδωτο ατσάλι, με χοντρή σίτα. Ότι πρέπει για ελαιόλαδο και καυτά υγρά, σιρόπια. Το σωληνάκι που μπαίνει στο μπουκάλι είναι πρεσαριστό δεν είναι κολλημένο.
