Generally: Lower temperature by 25°F and set cooking time to 80% of the middle of the recommended cooking time for conventional oven instructions when cooking using air fryer mode. This usually gets you in the ballpark, but with a minute or two to go, you might have to stop it or add time. I've been using that method from the beginning, and it has served me well.The two trays are perfect for cooking for one to four people. Beyond that, you would probably be better off buying a larger single basket air fryer or even two of you need dual options.As you'd expect from Instant, the machine just works. I've only tried Air Fry, Bake, and Reheat modes. Looking forward to trying Roast, Broil, and Dehydrate. The synchronous cooking modes work generally speaking, but it seems a little kludgy. Even if you set the baskets to finish at the same time, they often don't. I'm only talking about a matter of seconds to maybe a minute apart, but it's annoying. It seems this is mostly caused by the preheating cycle taking different times, or if I leave one tray open longer than the other. I guess that's more of a user error though.I have made the usual fries and chicken nuggets (beautifully cooked). I also baked a loaf of bread (frozen preprepared dough, thawed overnight, then baked) that came out delightfully brown and crackly on top but slightly undercooked in the middle (my first attempt, so it's probably me).I love thawing frozen breakfast sandwiches and burritos in the microwave for a half their recommended cooking time, then throwing them in the cold air fryer, setting it for 3-5 minutes at 350-375°F, and letting them brown and crisp up. You can easily fit up to 4 using both baskets. They are so much better than in the microwave or toaster oven and so much quicker than baking.I made a meatloaf from scratch, and it was the best I've ever made. It was one of the first things I made in it. I was worried about the food burning or getting stuck on. I did use a little cooking spray, and everything washed up with ease. The bacon and sauce had an amazing crispiness to it that I could never duplicate in an oven.I've made a few frozen pizzas in it, to. First, while the air fryer is preheating, I score the frozen pizza in half with a pizza cutter, then I cut through the pizza and the cardboard with kitchen shears. When the oven is ready, using the cardboard, I slide one half into each tray. Freschetta Naturally Rising Crust is my favorite, but you have to fold the end of the pizza to get it to fit, and then it rises, making it tricky to get out. Other smaller pizzas for better and are easier to get out.The trays and inserts are easy to hand-wash, and the trays HAVE to be hand-washed, but the air fryer inserts are dishwasher safe, and I've done that twice after cooking really messy dishes.It does take up a large chunk of counter space, but since I use it pretty much every day, I don't mind. The back of the unit did put out quite a bit of hot air, so I don't keep anything heart sensitive nearby. It fits nicely under my cupboards. I usually keep a pair of tongs on top so I can quickly adjust food or grab things out when they are done.I have it 5/5 stars in everything except for "easy to use". That one missing star is because it has so many options it can be confusing to learn, and the synchronous cooking either doesn't work quite right or is so confusing I can't get it right. Also, the beep tones are really quiet, and it's easy to miss the prompts to insert the food or turn it. If you're not in the kitchen, you'd better set your own timers to keep track. This is one case where a "smart" controller on my phone would be super handy to tell me when the oven is preheated, to add food (wait, I'm coming!), when to turn it (or tell it the food didn't need turning), and when it's done. That will probably come out in version 2.0 and add $50 to the price. 😁It did have a funny smell at first, but it's gone away after a month of regular use. Cleanup is easy. Size is good for me for most things. I probably wouldn't try cooking a whole chicken in it, but 2 game hens would be perfect!Overall, I really like this unit and recommend it for individuals, couples, and small families that like to cook multiple things at once. Do look for a good sale. I got it on Prime Day, and I'm happy. I might be less so if I'd paid full retail price due to the small size when I cook for friends or extended family.
