To say it first: A very good device. I use these four weeks ago 2 kettle now times a day. The level can be viewed from both sides, so well suited for left-handers. The power is such that at max. Filling the water boils in about three minutes. The unit switches off only when the water is boiling, so nihct if one removes the stove in advance, which does not bother me, because I prefer to boiling water. Apart from the hot plate, no immersion heaters, all made of plastic, so the Clatronic is against the metal cookers, my predecessor was one, very quietly. No plastic smell, not a time to unpack! Even pouring goes off without problems and spills, even if you want to fill a pot quickly. How long the WK 3452 is doing its job, I of course do not know, but I can no ifs and buts recommend.
