We are very happy with she stove's cooking and baking performance but very unhappy with its ceramic cooktop, which is ridiculously fragile.  It claims to be a type of glass, but is too sensitive to for standard glass cleaners, e.g. Windex.  So you are relegated to having to use special cream polish, which is mediocre in dealing with grease spatters.  Further, you're out of luck if you want to use your beloved cast iron ware that has been in the family for generations.  LG should engineer and make available a rugged cooktop as an option.
