The technology of the device is limited to a switch with the positions 'A' and 'Off'. So far so good. Pressing the switch before connecting to the electrical outlet, so it remains in the position 'On', regardless of whether water is in it or not. Thus, the heating plate runs (unintentionally) merrily to himself, to crown it then notes that the heating process is manually interrupting principle not! I have pushed about 20 times on the switch (with increasingly firmer pressure) because I already stood beads of sweat on his forehead, and at some point the thing but went out (coincidence? For a fixed pressure?), Although still was splashing some water. Then read it no longer turn on. Only after some cooling it went again. The temperature switch is appalling and there are apparently no electronics that controls the on / off (or the heating process). Who designed the this kind of stuff? I see this property as a serious security problem and can not understand that such a thing may be sold at all.
Another problem. the design of the measuring cup is extremely failed. The label is practically read and for the 'right' amount of water is always of the view in the manual needed. The device is also very light in total, which is why you have to be tenderly at power so as not to move the machine.
CONCLUSION: Stay away !!!
If the on / switch-off (with existing emergency stop) function, the unit would hire 10 Euro value, the current status of the device is unacceptable and should be avoided if possible, since the on / off or does not work reliably, thus represents a significant security risk
