Went with the Ninja 10 in 1 off Amazon for $249 DT551. Have the basket version and use it everyday. Hope to eliminate the toaster oven, toaster , and basket fryer for 1 device. The brand has held up well for us.

I purchased a Ninja Prestige Smart XL air fryer oven from Best Buy. Normally $429.99 and still on sale for $279.99. I got it for $249 on Black Friday. Yes it’s an expensive air fryer and oven style but I like it better than the basket style Ninja air fryer I had that finally quit working. I can cook more food at once and the air fryer function works just as well. It also has a thermometer probe you can use to cook food to the exact temp you want. I cooked a whole chicken a couple of weeks ago and it was falling off the bone using the air roast setting. Only complaint is that it’s a little harder to clean. Most of stuff it comes with is hand wash only and the glass on the door gets greasy fast. But would 100% buy again.

I have the ninja smartXL and it replaces just about everything I do in the oven except bake bread. Only because I bake a few loaves at a time. I would 100% go for it. Less heat in the house too.

Imam ninja foodi xl sa 2 korpe, smart verzija. Najčešće spremam piletinu i pomfrit. Ubaciš čitavo pile, ubodeš termometar i to je to. Ima recepata milion, spremaju ljudi svašta. Recimo bilo šta svinjsko ne volim stavljati u airfryer jer mi bude suvo, dok piletina bude savršeno sočna.

They sell this exact model other places as well. Found it at Costco, returned it and bought it from Woot for 40 bucks less. Its a great machine, no regrets. Ninja 10-in-1 Digital Air Fry XL Oven https://home.woot.com/offers/ninja-10-in-1-digital-air-fry-xl-oven-3?utm_medium=share&utm_source=app

I just picked up a Ninja Pro 10 in 1 and think it’s awesome so far. I’m picky about my kitchen equipment too.

I read point 2 and love my toaster ninja xl airfryer oven and than my basket style because of it’s versatility.

I imagine “best” is a matter of trade offs and perspective, just like most things. Our Ninja XL has completely replaced our full-size oven, we love it and use it almost every day. There’s a really cheap air fryer in my office’s break room, I realize sometimes budget is the most important thing for some people, but I would never buy something like that one that rarely works, cooks uneven, and looking at the melting plastic parts it looks like it’s going to cause an emergency someday.

I have the Ninja XL and love it, however, you might want to consider just buying one you like with an extended warranty. Normally I avoid those like the plague but they make sense for something like this. Get a 4 year warranty on a $150 AF, knowing with high usage you will cash in.
