As has been stated in other reviews: this kettle emits many sounds. I wanted a kettle with little or no plastic to avoid swallowing a little bisphenol (all kettles "classics" are shielded from this endocrine disruptor). All metal kettles, including this one, have a plastic gauge.
I chose this as the best Bestron classified according to the different tests. Does not limit temperature programming. By cons, like all programmable kettles, a delta of + 5 ° C.
