Is buying a kettle worth it?

Online Answer
Electric kettles certainly have a lot going for them. They are energy-efficient and heat water quickly (more quickly than in a stovetop kettle or in the microwave). You can even control the water temperature on most of the newer models, a feature that tea and coffee aficionados love.
