I was surprised to find how simple this was to use. Instructions even provide information on which settings, trays (see picture for included ones!) and rack levels to use. For someone who used to never cook, I'm finding myself much more willing to do so with the ease of this oven. It doubling as an air fryer saves me valuable counter space too. The drip trays are perfect for easy cleaning too. The only minor note I'd warn about is the heigh limitations of the two ovens. See my picture for a soda can size comparison. You won't be able to fit anything too tall in either oven.
