I bought a Kaiser electric ceramic hob a few years ago. The first one we had was faulty. The second one worked ok but is a very poor design. It has the word 'Intelligent' written into the ceramic but in my opinion it is the complete opposite of that! First of all it controls the temperature using a simple on and off cycle rather than thermostatic or using variable elements like some other hobs. This makes it difficult to control the temperature. The most absurd feature of this hob is that when you want to turn one of the rings down and if the ring happens to be currently in an off cycle, it turns the ring back on - the complete opposite of what you would expect or want. Surely it is not rocket science to have simple firmware in the hob that starts the cycle in the 'off phase' when it detects you have lowered the heat and in the 'on phase' when you increase it. I was fooled into thinking that a German hob must be good but I think I have learned my lesson.
