I purchased my first Breville products 10 years ago when doing a home reno and having no kitchen. Toaster kettle and oven and was delighted with all. Recently I was thinking I needed a new oven the controls were starting to slip a little.I saw some advertising for the oven with air fryer,  not knowing what to expect I purchased Breville BOV860BTR. as well as a recipe book. The air fryer still uses oil and I could get the same result from the older model using the roast or bake function. Following the recipes in the book was a disaster, calling for the basket to be shaken resulting in pieces of Panko flying all over the oven and burning on the oven surfaces.My new oven now looked older than my original 10 year old one. I still think you make great products and will be a customer but please explain the air fry function.
