If one reads the reviews here, one gets the impression that some downright impossible expect from a kettle he should be without plastic and still have a water level indicator, it is to heat water, while his best water-repellent, otherwise have to see because water stains are, he should bring to a boil, but most completely silent water ... Such miracles do not accomplishes this kettle, but he is the best we've had so far - at least until now. First of all - it looks very good and high quality. From design a clear recommendation. The smooth surface makes it, of course, somewhat more sensitive to stains, as bad as befüchtet, but it is not, especially since it can be cleaned quickly and easily (you would not believe it, then disappear any stains). It heats the water quickly and meanwhile lit a blue indicator light. Switching off one hears hardly (our old has cracked this quite loud, do not do this). Filling and pour doing very well, the lid closes perfectly. Perhaps a small amount of water remains in it, somebody noticed like here, but that's damn me if there might still 10ml stay inside. Therefore, I do not miss the water level indicator. I had already disregarded the old, who had a. I do not measure just exactly 0.7 liters from, but doing it by feel. A maximum level indicator on the inside there is the way to ensure that the boiler is not overfilled. Now for plastic, rubber, etc. Our old boiler was made of metal, however, had a large water level indicator from quite soft plastic. When boiling water that has strongly smelled of plastic, as if it were made entirely of plastic. Therefore, this time I wanted a with as few plastic. This is the case with the Russell Hobbs. Inside, only the holder of the screen hard plastic is (this can be deduced very simple and clean, big plus). Silicone I could not find anywhere. When heated, there was still a slight odor coming. This stirred but in my opinion more of a rubber gasket ago that surrounds half of the upper part precisely on the cover and is significantly lower than other kettles. After a few times cooking this is as good as gone. The cable is long enough, in any case not shorter than in the most of the other kettles. Conclusion: A residential water heater with good removable sieve, which heats the water quickly. Plastic is installed only in this screen. Overall, highly recommended.
