Air fryer was a gift based on my research.  This is my first air fryer and after deep reviews & considerations, I aked for this one mainly because of KitchenAid name. Instructions for use are terrible.  Instructions should include suggestions for all of the functions.  It's a trial & error process.  A tiny cookbook could have been included.  There should be a button to PAUSE cooking so one could check the food, especially for learning the machine.  A light buld would be nice when you open the machine.  A tool to pull the racks or trays should be included because they are hot.
