First used this morning and bought it for the large surface area to do pound of bacon in one cook time. Heat level is at least 25 degrees less than my old one to do the same job as it retains heat better than the older material surface. 'The rock' feature is better than the old teflon coating and probably safer too from ingestion of the coating. The handles are too high making sliding shelf storage less convenient than the old one though. though. [This review was collected as part of a promotion.]
