Product review (4 stars): Great, but 4 stars.
Great, but enameling is not as great as original Jenn-Air, 1990.  1990 one was great until now.  Vinegar from pickling etches top if it sets there, but is not hardly noticed.  Cannot buff out etching from acids.  There is a warning in the written materials as to this, but I did not read carefully.  Poor me.  Unit from original Jenn-Air was heavier, resisted dirt and stains better, and more square.  But, this is really great, wish I had ordered two and kept one away for when we sell the house. Wash with clean soap cloth, rinse, wipe with lint free cloth.  Looks great!  Would buy again.  Love my cook Top.  July 5th, 2016 addition.
New information:  Coils only operated for  17  months.  Don't know what the life expectancy is on these coils, but it should be better.
I now have to order two new coils for this unit.  Basic unit operates fine and looks great.
