The heat from the large burners are very efficient in heating pans and boiling water quickly.  The small burners are low enough to simmer.  Unfortunately, I noticed the heat control knobs have a bumpy/rough finish.  The first time I cleaned the stove with a soft sponge the silver paint is coming off.  I have started to cover the knobs with a towel (I know-dangerous) so I don't have to so softly clean the knobs.  Worried the painted temperature indicators around knobs will wear off as I have seen on other stoves.  Although I love the look and function of the big, heavy grates you have to be so careful to place them exactly on the little rubber pads or you will scratch the finish of your cook top.   Whenever anyone offers to help clean up I have to pass so they don't wreck my stove.
