I purchased this year or two ago and have been very happy indeed with it. It is the best electric kettle that I have ever owned or used. Here are the reasons for my rating:
Cordless, light in weight, the lid opens wide with the press of a button, easy to look inside and check for lime-scale build-up, very little limescale buildup in this kettle, easy to remove filters and clean them, easy to buy replacement filters, easy to clean inside and outside, water boils quickly, turns it self off quickly, and quietly, and not too noisy,
