Our old air fryer died recently and, even though it was highly rated, we had gone through 2 in less than 3 years.  When the second one died, I felt it was time to change brands.  We have never been disappointed with KitchenAid appliances and still have some of our original appliances from our kitchen remodel 27 years ago.  Tis machine is attractive and much larger than our previous oven.  So far, we have used Bake, Broil, Air Fry, Toast, and the temperature probe.  All have worked flawlessly.  Our older unit was faster but, if you didn't stay on top of it while using it, everything would burn.  The Toast function takes a relatively long time but it otherwise works well.  Air fry also takes longer but there is no flipping and the results were great.  I am very pleased with every aspect.
