So far this range has performed like it should! The first time I used it an error code displayed and the oven shut off. I googled it and it said to cut the power, wait 30 seconds to reset. I flipped the breaker box and followed the instructions and nothing has happened ever since. I do notice a few little bubbles in the area of the large burner. I can tell you I have been a little old while using the oven and cleaning it so it wasn't because I was being a "rough" cooker. So far I've only cleaned it with a little dawn on a hot microfiber cloth and it does an excellent job. I follow with a dry cloth to make sure I don't have any water spots. It's a very nice looking range also.
 I would give this range 5 stars if the bubbles weren't there. I feel after my fourth use, using high quality brand new pots and pans with a smooth bottom, and me being extremely careful not to damage the surface, the range burner areas should hold up better.
