I thought this would take a rocket scientist to figure this out, but it was really easy.  I started out slow by making toast.  That was a trial and error figuring out where you need to set the dial for the toast you like.  Makes great toast.  Doesn't dry it out like a regular toaster does.  Then we graduated to air frying some pork chops.  That was quick to figure out too.  Just follow the directions from the recipe and you are good to go.  The pork chops were the tastiest, juiciest chops I have ever had.  It didn't dry them out.  So good.  Clean up was simple. Did it right away so the trays wouldn't have time for the food to dry on them.   Drippings wiped up easily, trays didn't need to be soaked.
