Before I bought this style cooker, I have read many reviews and comparing. The kettle does with the glass and steel of very good and is completely odorless. And it's fun - I am always happy about the blue lighting on heating of water. I need very often hot water. Sometimes quick succession. Unlike the previous heater with thermostat, he does it willingly. The old man has sometimes kept me waiting minutes for the sensor of the thermostat was finally cooled. Also great: I can see right away if my Britta filter no longer filters out the lime. In very hard water you should always filter the water by the way. Otherwise illuminates the play of light and the lime! If you have to descale it once: just take a little citric acid. The only thing that looks somewhat sensitive, is the on-switch of Plexiglas. But according to him then pressed gently down ;-) Absolute buy recommendation!
