I bought this kettle at the beginning of the year and at first I was a bit skeptical as it was a lighter weight of stainless steel than previous kettles. But I am surprisingly very pleased with it. It's the easiest kettle to clean. Every morning I boil 6 cups of water, then subsequent cups I only use coffee option (just comes to a boil). Every morning I also clean any scale buildup before filling with a long handled thin brush. When finally I can't remove enough of the scale that way, I take the filter out and put in the water that's left, put a little bit of vinegar in it and voila (!) it takes it cleans it perfectly! Then I rinse it out a few times and leave the lid open for a bit to make sure the vinegar smell is gone.  I am so impressed...what an easy kettle it is to maintain. Not to mention that it is also a nice looking addition to my kitchen of other Ninja products.
