While I have only had my new oven for a few weeks, I find it to be extremely easy to understand. It is extremely quiet, which is a blessing. I believe that it is also very accurate with temperatures. I am still trying to experiment with the Air Fry option--I think that it probably needs to have a tad of oil added to whatever you are frying--but hopeful for eventual good results. I really like the large lettering on the display! You can see the time across the kitchen!
