Now to the point, which is why I did not hesitate to buy this product, is here so often mentioned beep. So the one or the other review after I have been expecting a speaker "o sol e mio" beeps when it's done, I certainly have enforced me and simply ordered to try it themselves.
The kettle beeps both at power up and when it reaches the desired temperature. The acoustic signal is limited to a simple "beep" of less than a second, in a reasonable volume, to my mind cook other devices louder. To compare this might be the "bing" of Microwave. My 5 month old child does not affect this sound anyway. The tone at power is perhaps unnecessary in most cases, but does not bother me further. I hope this one or others in their purchasing decision helps, because I personally was very confused at the reviews on this tone.
In summary, whom the "bing" of its Microwave does not bother you, I can give a 100% buy recommendation,
