I bought this cooktop in December, 2017, so I've only had it for a little over a month.  So far, I am very pleased with it.  The burner sizes and placements are my favorite feature.  It heats up very quickly.  It accommodates all my pots and pans sizes. I am hopeful that it will not scratch or chip easily.  So far, so good.  I am careful since it is so new but as I get accustomed to it and relax about it, I hope it will continue to be durable.  It cleans up nicely so far.  I like the invisible touch controls.  So nice not to have to clean around the protruding type. I have to figure out how to stop hitting the touch controls accidentally as I have inadvertently turned off the burners or changed the temp.  All in all I am very pleased with this purchase.
