Product review (4 stars): easy to install
Installed only a month so... easy to install,  controls work well.  Easy to clean (!), both large burners really put out heat. Issues: (1)cast iron grid holds pans about 2-1/2" above counter, would have preferred it to be recessed more; (2) the cast iron grids are spaced too far apart to adequate support 5" or smaller pots, makes it difficult to use more than the two outer (largest) burners at the same time since small pans are at risk of being tipped or accidentally pushed completely off. We always have a 12" cast iron frying pan out,  and anything larger than about 7" just won't fit on the smaller  (front and rear) burners with it. Heats up a large pot of water really quickly, though
