Kettle boils water 1

I would like to know what some people expect from a kettle ...
Here are a few words of explanation:
This unit boils water. Water (H2O) is present at room temperature in the liquid state. It is heated to about 100 ° C, it is in gaseous form. Therefore, the gaseous water in the form of bubbles comes out. This process generates noise under standard conditions.
Therefore, this device is not silent!
As just mentioned, the water begins to boil at 100 ° C. The side walls of this device (such as hard to see) is made from glass. Glass has a higher thermal conductivity than most plastics. Therefore, the side walls during the operation; fairly quickly; up to 100 ° C hot.

So, now that that's out of the world, now to the actual review:
I think the kettle both visually and functionally appealing.
Only the handle looks a bit unwertig, especially the buttons are not made precise fit.
Water is just cooked quickly as in other kettles, however, the water barely comes on this model with plastic in contact. Only when pouring the lid is in the way (which is made of plastic)
The included manual is not available on China Deutschisch resulting in that I have no idea to this day as the "warm function" can be used. To set the temperature you need fast + or only after pressing the POWER button - press.
The temperature selection works relatively well, but the unit is not regulated.
Clean I do my kettle eh only with vinegar: vinegar with water in, wait for 1 hour, then rinse with cold water ready. I do not have my hand in there, if you want to make sure, however, it might be close.

Oh ... one more: The beeping!
This unit beeps. It will beep if you put the kettle on the base. It beeps when you turn it. It beeps when it's done.
The beeping for finished I find quite well ... the rest just annoying.
