I purchased the range/stove approx 2 months ago and have come to believe that this was a big mistake.  The stovetop requires gentle use and care.  The glass stovetop is easily scratched by sliding pans.  You also need to be careful not to drop a pot or you could crack the glass surface.   It is also difficult to keep clean, you really need to use elbow grease to get the smallest of spills out....moreover, it requires constant cleaning (black shows everything).   The oven works great, however the "Easy Clean" feature is useless, does not work even on the smallest of spills.   All my appliances and TV's are LG and I love them all, but this stove gets a big thumbs down for me.   Sorry LG.
