Actually, I have the kettle ordered glass because I did not want any softeners in my water. Unfortunately, the cover is made so inferior materials is made, that he smells of plastic extremely even months later - a sign that regularly when cooking water dissolve toxic substances and plasticizers and thus mitgetrunken course. But, I should not fret - because for 20 euros you can not expect high quality workmanship! Now there a new, more expensive kettle - the dues paid.
