Product review (5 stars): Cooks and looks great - after sixteen years
I have had this cooktop for over sixteen years and it still looks new and works great.
As with any ceramic cooktop, it needs to be cleaned.  Over the years I have had no problem doing this - sometimes with Easy Off, sometimes a good scraper blade and most often with paper towel and soap for any spillage.  the trick is cleaning it from a burner before cooking on it again. if you do cook where there was spillage, it takes more elbow grease to clean, but I have zero staining after all these years.
it cooks fine once it heats up.  the time it takes to heat up is a bit slow (maybe three or four minutes) but I don't know how it compares in this regard to other ceramic cooktops.  If you want a fast heat-up time, you should get an induction cooktop (or gas).
