We are so pleased with this cook top.  It replaces an Electrolux Icon that gave up the ghost after 15 or so years.  We love the knobs and will be much more satisfied when the granite yard gets the frame installed on my counter so the cook top won't fall through the hole that was cut for the Icon!!  This cook top is quiet and cooks evenly.  Love the bridge option that allows use of two elements for griddles or large pots.  Have been using it only a couple of weeks, but can see that it will be just what we need in our kitchen.
