Water can boil the Dualit Architect: For four cups of water it needs about 3 minutes without large to make noise. The steam maintains the cooker while with him. Very nice, not fogged tiles and windows. Also convenient is the Kalksieb, which prevent Kalkkrümmel in tea. The screen can be easily replaced. The kettle is heavy and very large. Therefore, the stainless steel design is striking. Who rarely cooks plenty of water, has little space in the kitchen or wants a decent stove, should better look for another kettle. The prominent lighting of the stove in the active state is convenient because you know immediately that the stove was also turned on, and then heats the water. Unfortunately, the cup display does not match my cups. Liter figures would have preferred. The digester to slide easily on the charger device. When Wassereinschenken have to stop the boiler, since otherwise the water display obscures my hand and not looks. The price performance ratio is rather poor for my taste.
