I have owned this kettle for a year now. Unfortunately it has now lost its shine. I have tried cleaning it but it makes no difference. I would not describe it as an ultra fast boiler. It can boil 2 cups of water in about 90 seconds and if you fill it to maximum it takes about 5 minutes. Calcium deposits have built up around the rim and the spout but the filter does a good job of preventing these deposits from entering your cup. The light inside the kettle is hardly noticeable and is a bit disappointing. The cup level indicators are still visible, they have not worn away, its just a bit disappointing that it has lost its shine probably due to hot oil spitting from a nearby skillet on my induction hob. I say that because one side is dull but the other side is still shiny.
