This hob is useless if you cook with liquids. The control panel is so sensitive if the pan spills a drop of water or you have wet/damp hands that touch the control panel it will reset the setting or turn off completely. You can't leave the pan simmering and leave the room because when you come back it has turned itself off. The fast boil setting is vert slow and again will alter to w lower setting well before boiling - Pretty useless as a hob.
