The ceramic hob is not suitable for serious cooking. It actually has only two levels, on and off. When I make a choice but heat setting 9, the ceramic hob switches to constantly on and off. Thus, it makes cooking with a thin-walled pan an ordeal. My omelet is done too quickly constantly cold at a low level or high level. The same applies for example. For mocha. Incidentally, the surface scratched unusually fast. The oven has convinced us, however, so the second star.
