A cooktop with a mid-range preparation quality always has a child safety lock. This is useful, because it allows you to prevent your children from messing with the buttons. If you want to quickly bring a pot of water to the boil, use the boost function. This function is also present on all devices in this range. Do you want to set up the cooktop to your own liking and as precisely as possible? Then choose a cooktop with a high-end preparation quality.
