The kettle has a removable scale filter. The trial removal of the filter and reseating was quite a fumbling, but I think if you did that a few times, it's even faster.
The kettle is stable and secure on his heater. The lid is easy to open and the pouring out of the water I had no problems. Something I found inconvenient attaching the water level indicator under the handle. Since I had already think about how I have to hold the device now, to see the capacity of the water during filling. At the base or under the base there is a cable winder. The insertion of the cable in the winding requires some concentration. But if you perhaps tucked the kettle in the kitchen cabinet, then it's handy when no cables lying around. In this respect, the manufacturer has thought of something.
The device is provided with a protection against overheating, which is quite handy if the water is boiled again unintentionally. When the water boils, the device turns off by itself. One can also stopping the Aufkochvorgang already manually, which is important because every now and then I prepare green tea and for the water to be hot and not only a lively boil.
