Over all I am very satisfied with this product.  Cleaning after air frying is my only criticism.  There are "guards" over the heating elements and they get quite greasy after air frying, and they are a bit difficult to clean.  If they were "removable" for cleaning, it would make things a bit easier.  The appliance performs great in all the functions, and honestly, this is a minor issue, but perhaps the manufacturer could make this modification in the future.
