We have one by Siemens. Works well, and I like it. But...
(1) If you spill water on the touch controls it stops working with an error message until you dry it.
(2) Several of our older copper and stainless steel pans would not work. T hat is to say, the hob refused to power-up because it could not detect the pan's presence. It does this detection using a magnetic detector, even t hough induction heating would work fine for these pans.
