... For about 3 months of continuous use. I bought this kettle as a replacement for an old, dilapidated predecessor with a lot of plastic. The device makes primarily what it is supposed to do, namely water hot. It can be super clean through the small plastic portions but and keep sparkling clean. The small stage division inside makes it possible to portion of water for 1, 2 or 3 cups, wass significantly shorten the cooking process. The staff are enthusiastic.
