I usually heat up water using my microwave.  Since I have discovered the HB kettle, my life has changed. I can heat water for multiple cups of tea when I have friends over. It is a sleek looking machine and heats water to a variety of temps. I can set it for my green tea day or for my hot cocoa days. It comes in handy when I need hot water for instant oatmeal and to make broth. How did I ever live without it?
