Have long been looking for a kettle, which is affordable, isolated (wg. Of children) and not ugly. This dual solution works just fine and met all my needs. In particular, the water and the interior do not stink like plastic, like the (brand) kettle that we had before. They had always given me a bad feeling about the use of water. Although a small Nupsi / pin plastic mounted on the floor (probably part of the temperature gauge), and the cover is also made of plastic, but the does not come directly into contact with the water. The rest is stainless steel. The R & S-kettle sits comfortably in the hand and is really outwardly barely warm, but keeps the content quite a long hot, so you do not have to cook twice, just because you have short forgot to put the tea immediately. A nice side effect: The thermos lid trittt cooking from not all the time water vapor. How the lid closes (here there is only one small area where the cover is locked) has quickly the feeling. I am very pleased. The only wish would be for something more performance. The cooker is quite slow compared.
