I was really intimidated and a big overwhelmed when I first got my Combi cooker. There are just so many ways to use it and a LOT of instructions and different times and settings and tray combinations to use. I have now tried many of the settings and it isn't as intimidating but I still have to refer to the included booklet before I use it. It does a wonderful job cooking, the air fryer makes everything golden brown and crispy and I love using it to cook roasts. The accessory trays are very easy to clean and very, very non stick. I love having the ability to make an entire meal at one time with minimal clean up, quick!
