Yes, it heats up quickly. When it beeps you would think that it means it is at the temperature you set. Using an accurate oven thermometer, that is not the case. I am getting about 90 degrees below the temperature setting at the time of the beep. I wait another 15 - 20 minutes to get to the temperature I set. Being a new range, I am still using the thermometer to learn it's habits. There is a calibration adjustment on the range for 35 degrees plus or minus. Changing that also changes the temperature when it is at full temperature. I had to adjust mine up 5 degrees. Deceiving and not happy about it. Why beep if it is not that hot?
