Now that he has been tried properly, I'm sure. It was a good choice.
The kettle is used on a ceramic hob. There's no problem. The water boils quickly and the drink (in this case, coffee and tea) tastes very good. There were also visitors several times praise for it.
He whistles maybe something silent. But you can hear well in a full-size apartment, when the water boils. Moreover MNL should anyway not as far removed from the stove.
So I can recommend buying this boiler.
