I have the double induction hob now for 4 months and would have no more. You can sit and watch the water while cooking, as soon as possible. I first wanted to buy another cooking surface, as 190 yes today is a lot of money but it was worth it. It write so many on induction, one can thus only make hot food quickly or bring to a boil, but I have already repeatedly let dishes with it simmer at low temperatures - it works wonderfully. When warming up you should Allerding stop there and always stir, just to go really fast. The already several times mentioned fan bothers me really only when you turn off the plates (it is then subsequently cooled), but since I do not eat in the kitchen, it is not relevant to me. Conclusion: Eat warm very quickly and saved a lot of energy - so it must be.
