As a confirmed tea-drinker, I can tell you that this tea kettle is a game changer! I have never been able to calibrate the water temperature for each type of tea except by hovering near my old kettle and guessing. My husband, who always thought green tea tasted bitter (because I heated the water too long), now raves about how “buttery smooth” green tea tastes. My other tea kettle still works fine, but after trying this one at a friend’s house, I had to ask for it as a birthday present and I’m never going back!
