Have used range for a month. Polish it every day with ceramic cleaner. Once completely clean buff it with a clean paper towel.  Glass looks shiny and new. Have been super careful to put pans directly down and up so as to not scratch it.  I have not scratched it (the glass is not scratch) but appears to have a very thin black coating on it that has scraped off in a couple of little like nicks where the metal pan first touched the glass.  So now the very little nick areas are no longer black but a silver color. Pattern is still in place and glass is not scratched but black color is gone.  I like the pattern but am concerned how the missing black coating is going to multiply and look over just a very short period of time.  You have to get your finger just right to get electronic buttons to go so a bit of a pain and up and down arrows instead of a number pad is a bit of a pain.  Other than that it is a good looking range and functions very good in all other aspects.
