I’ve only been using my new oven only a few weeks.  I’ve been very pleased.  I’ve only used the regular baked and air fry.  The air fry works great and cooks in less time.  You barely know that it is cooking. It is so quiet.  My food is done in the specified time.  I’m anxious to start using all of the different functions.  I especially love the knobs to dial the temperature and function.  The glide rack is great also.  I love that you can move it around to different levels.  I do have to remember to stand to the side to not get a blast of hot air in my face.
