The kettle heats quickly (~ 3 minutes for its ability MAX) and the water did not taste of plastic (in order to silence the comments I have read on this subject)
Otherwise, the resistance is round, flat and white but I do not know what material it is what ensures to date a totally nonexistent oxidation. Nothing like heat pipes iron models that I knew
If it holds like that over 2 years I will put 5 stars.
