I've had this range for a month, and I love it.  I have used the regular bake and convection bake options and both work really well. The convection bake is almost like having a double oven, because I can put two trays of cookies in at the same time and both sheets come out evenly baked. The air fryer works great, though it requires an accessory that you have to purchase separately. But it is really worth it, and I gained countertop space since I could remove the countertop air fryer! I've cleaned the oven once, and again, the feature works great. The only negative I have is the tier. When the timer chimes at the end of the bake/cook cycle, you cannot just press the "+" button to add an extra minute or two. You have to turn off the timer, then turn it back on and add the time you want. It doesn't affect baking or cooking. It is just a change that required time to adapt my behavior.
