In the kettle Selection me this was important: - Low emissions - Temperature option - Cooking time - Noise With regard to low emissions I specially bought me a review at Stiftung Warentest. Since this cooker (however, some others also) make any of the tested pollutants according to the test report it came to the final round. I always thought it would be a stainless steel boiler, which would have to be safe in this respect, but that seems not at all times to be so according to my research ... The device is working properly, when the cooking time're all about the same, if you choose 80 or 90 degrees, then it goes pretty fast. The Geräuscch cooking can be heard clearly, but does not bother me. The built-in beeper I find too loud, annoying the startup sound, and at the temperature range, it really would not be that is beeped when operating. When switching off that's ok, in my opinion should be deactivated but (if I cook breakfast at 6am tea and the thing all still sleeping wake ...). The unit needs no standby current (I also measured), it would be assumed so, but is not at all so !!! Now for the really only real gripe: In the first phase I always after the nose cook reingesteckt and found strange odors. This is fully blown after a few weeks, but has really worried me at the beginning. I have the cooking cycle has to be set not counted it, but a few dozen, it may have been already. Having the deodorization now behind me, I am very satisfied with the device!
