I am not an expert cook, just a regular, get dinner on the table kind of cook. Have been using it for about 6 months. Getting used to it and the new cookware I had to get. It has been an adjustment. Burners definitely hum. Pot of water boils quite fast if you use power boil. I  make crepes in a steel pan, but the edges don't get as brown which leads me to believe that the element is smaller than the lines indicate. Overall, it is fine for my needs, but not great, hence 4 stars.
