We use our kettle 1-2x daily. After about 6 months, a small screw was after the prescribed descaling the kettle. For me, unfortunately, not seen where it was installed? I would not imagine so; if someone does not notice and etc in a tea or baby formula mittrinkt or eat? Illumination of the scale and the Einschaltgriffes since precipitates from & to. Vl. Is there a connection. My conclusion: A kettle from WMF for about 50, - no longer promises to be one of the discounters for 19.99 Probably was therefore the price is already significantly reduced. From me there is no purchase recommendation for this kettle. I'm disappointed.
