After several weeks of using the new oven, we're finally beginning to be successful with the oven,  We're experienced toaster oven people, but initial attempts to follow the recommended settings resulted in overcooked and in some cases, burned food.  We found that air fryer recipes were done in half the time and charred around the edges.  However, if you lower the temperatures to 350 to 375 degrees, food cooks through without burning.  We're now cooked hot dogs, burgers, filet mignon and pork tenderloins which are better than grilled.  Sweet potato fries are excellent at 350 degrees, just keep an eye on the time.  Use a digital thermometer to make sure meats are done to your liking.  
Overall, we're pleased with the purchase, now that we're getting used to the adjustments.
