I haven't had the unit long enough to be 'factually truthful' regarding my review.  However, from being installed there are a few things that are - in my opinion - lacking.  1) I do not like the fact that minutes are in increments of 15 seconds.  2)  Haven't figured out why I must tap the 'start' button twice.  3)  Would prefer that the panel was lighted.  4)  The Biggie:  Instructions for use or either complicated or lacking. 5) Have used the Air Fryer a couple times but have to teach myself how to use. 6)  Have yet to use Convection Oven.
