The non-stick with a steel plate sandwiched in aluminum also made strange high pitched sounds that drove my daughter nuts

This item emits a very disturbing high-frequency electrical sound when in use

Extremely loud high pitched sound makes my sinus cavities hurt

The sound has only gotten worse and happens every time it's used

I think its the sound of the magnetic field heating up the pot (which happens extraordinarily fast), but the sound is a little concerning at first.

In addition to this awful sound, it will stop heating in the middle of cooking

It makes awful sounds, like it is struggling for dear life and will die at any given moment
