We only used it 3 times so far. Each time, the food was done sooner than predicted, about to burn if not watched carefully. We haven't yet checked the operating temperature with an oven thermometer, but will. It seems we may have to cut 2-3 minutes cooking time off every recipe or lower the temperature. There's a definite learning curve to this, and the need to keep notes, but we having fun. This unit will allow us to easily make so many things we never tried or haven't done in a very long time. The accompanying recipe book and the Kalorik website appear are limited so we'll have to invest in the hardcover books specifically written for this unit and again see if we need to adjust times and temps.
