I find the digital dial, much more complicated to navigate than just having them displayed out on the front of the screen. If you need to go from convection to regular baking, or vice versa, in the same oven, you have to actually turn the oven off! Then reprogram it. This sounds like a very poorly designed option. This oven, although it fits in the same space as my previous Whirlpool oven, it is about an inch shorter on the inside, and therefore does not fit my cookie sheets! I had to get new cookie sheets to fit it! When, using the meat probe,  you need to put it in a cold roast before you start the oven. So how do you preheat it for the roasting time to be correct? There were no instructions on how to use the air fryer. There was no broiler pan. I would never buy this product again.
