Otherwise, the following features stand out very positively:
1) The lid seals Steam technically better than all other kettles of this type before! It takes nothing, so zero risk of burns
2) The shape is slightly more slender and less "bulbous" than some other models, so even minimal space-saving for my small kitchen. Here, the grip is not as expansive as some.
3) The stove switches sufficiently quickly when the water boils. (For other was with the cooking time a little exaggerated).
To all who have the "minimum amount of water" in the eye: that's what the marker ... but you can also boil water for only a single cup - only then should be near to a precaution to disable itself. This saves the way not only water but also energy. Times have a study from England read, according to which the largest energy spin is ever the kettle, since many heat more water than is actually necessary to. If everyone only a third would erhizten less, makes the enormous energy savings for an entire country - every day on New's. So the minimum mark is only important if you can not stop there / wants.
If the kettle also holds a little longer than my other (who have the Spirit each abandoned after about 1-2 years, for example, wg. A broken lid, a jammed lid or a broken on / off switch), then I forgive maybe even 5 star in retrospect.
Finally, a comment on the smell: I am hyperempflich when it comes to something like that, but the smell was initially much less than any other glass kettles, which I had so far. Still nice rinse with detergent, cover and shake endure, hence the lid from inside is cleaned something, then 2-3 times boil and discard the water. I smell any case nothing more.
