Digital controls are easy to understand and set. Timer adjustments are needed when baking to avoid overcooking, but the results are worth it. Basically, if your frozen dinner can be cooked in a conventional oven, you can reduce  the timer by ~10 minutes and prepare your meal using the convection feature. My microwave has been reduced to a soup and other liquid source. Food don't dry out or become rubbery in the air fryer.
Have cooked pizza, fish filets, toast, poptarts, over medium eggs. All were great with minimal cleanup.
The only con is the counter space it consumes.
