The first impression is not bad, on the contrary: The kettle does not just look at the picture look good. When pouring out the water has a pleasant feeling, the handle lies comfortably in the hand and does not warm up (as other reviewers come out is beyond me), you do not scalded by escaping steam. The latter is already happened to me with much more expensive devices.
At one point Mr. Rosenstein and his sons follow a modern habit: Just about everything you do with the boiler, will be accompanied by a completely superfluous beep. When the water has reached the set temperature and the kettle switches off, is equal to 15 times (in words: fifteen) beeped. If one of the cooker to the station: Beep! That the temperature is in a single-step: Beep! Merely holding down the temperature setting and the associated rapid passage through the temperature range are not accompanied by beeping. Since, however, as almost always passes at the desired temperature, the desired temperature in individual steps you have to then approach: beep, beep ... maximum redundant, annoying, noise pollution!
The lighting of the water when heated: Cute frills, fine for a Barbie dollhouse.
The operation is very simple, it requires no manual.
The problem really is the temperature of the water. The display itself is sufficiently accurate. With a thermometer, I have found a maximum tolerance of 1 degree, which is considering the amount of a good performance. BUT: If I set 80 ° C, the water is also apparently warmed to 80 ° C. About 5-10 seconds, after the stove has been turned off, the beeps part for the 16th time and the temperature display changes to a value of about 90 ° C. In principle, therefore, the effect described by the manufacturer (variable temperature from 25 ° C to 100 ° C) is obsolete. Luckily it's a short collection of experiences not too complicated to set a value at which the water has a temperature that is needed for a proper green tea.
I suspect, however, that other, more expensive devices are likely to have a similar problem: a temperature gradient between temperature measuring point and place the heating is inevitable. In addition, one must consider the inevitable inertia of the heating. This can possibly improve a bit, but not completely eliminate it. It could accommodate a stirrer in the unit yet, but that is no longer to do for 40.
Negative I have noticed that form in the temperature display water droplets. So far, the blue (not red) temperature indicator is still clearly legible.
Conclusion: The kettle is not worse than stinknormale devices without temperature control. Once you get the hang of raushat, he is responsible for the preparation of green tea (80 ° C), coffee (95-100 ° C), and so useful. In this respect, I can buy the device, despite the disadvantages described and the related deduction of 2 stars thoroughly recommended. I will not return the kettle.
Look at one, in the house Pearl you not only get so indescribably important things like window cleaning robot, USB missile launcher and loose inflatable Santas.
