I've been using electric kettles for about a year. Still like any
stove kettle they make the sounds indicating water temperature. My
favorite sound absolute silence before the boil and shutoff. My
previous Kamjove had a colored fill level so it was hard to see the
bubbles. My current SS Cooks from JCP has a prominent clear level
chamber protruding from the pot so I can see the size of the bubbles.
A couple of weeks ago I started to notice the steam coming from the
spout little,more,lot over the last minute and half till shutoff.
1500W doesn't waste time making water holy.
