Design prior art

Buying criteria were design / color and the water should not come into contact with plastic parts and rubber seals. Meets! The boiler feels wertig, looks elegant and fits perfectly with my other matt black appliances.
However, you should fill the boiler with a maximum of 1.5 liters of water. If filling up to the max. - Brand (1.8l) or even above transpires when heated slightly from water. I still could not locate exactly where, but guess at the level indicator or at the bottom handle approach. Now you might say, the few drops of water, not a problem, but: The leakage of water running directly off via the switch. As long as the well goes well ?! The observation from another review. you could be scalded when pouring, I can not confirm, there probably sat on the lid not quite fixed.
Conclusion: Design / processing 5 star, technology / security 2 star, total 3.5.
