I purchased this cooktop about 3 months ago but just recently had it installed.  It is very, very difficult to clean and it scratches very quickly.  I have tried using all the methods of cooktop cleaning but it takes me almost an half hour to clean it.  Everything you put on it scratches it.  I'll never buy another one.  And of course the insurance doesn't cover anything.  I have to enter the sweepstakes to try and get my money back.  Don't buy it. [This review was collected as part of a promotion.]
