The ETNA KIF680DS is a built-in induction cooktop with a flexible cooking zone. By combining the 2 cooking zones on the left, you make one large cooking zone. This is useful if you like to cook with long pans. If you want dinner to be ready quickly, select the boost function. This allows you to quickly boil a pan of water, for example. With the melt function, you can defrost your frozen dishes or meat. If the phone rings, you can pause the cooktop. This is easy to do because all cooking zones have separate touch controls. Simply push the button and the device will get back to it on the same settings.
