I have been using this kettle for a couple of weeks now. Living in a very hard water area  having the added feature of a water filter was just what I was looking for. I am amazed by the purity of the water after its boiled as my previous kettle always looked cloudy. I love the fact its a clear kettle, it has a tab on the top of the lid to show when the filter needs changing. It looks stylish and upto date with the added feature of small blue lights around the base which eliminate whilst switched on.
