I bought this about 10 days ago and am still getting used to the different cooking settings with time allowed for food. It's more of a use and learn for different settings and food choices as it cooks faster than most air fryers.
So far, so good as we have improvised on the charts in the booklet using less timing (wattage higher than my old air fryer). Adding more cooking time to my old recipes. No biggie!!
All said and done, it's very easy to operate. Love the double stack feature too. Also love that it has other options available such as roast, broil, bake etc. along with of course the air fryer option.
