Cup indicator: an indication of the amount of water that corresponds to a cup, to boil only the amount you need. This saves time and electricity. Special design for smooth flow of water without splashes. Water level indicator on both sides: easily see the water level - easy for right-handers and left-handers. Triple safety: automatic shutdown when the water boils, if you remove the kettle from the base and overheat protection. Operation with one hand and opening the lid with the touch of a button.
