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.

I have the prestige smart XL and holy fricking crap I love it. I can't ever go back to a standard toaster oven or combo. At first I thought it was way too big and now I don't even notice.

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.

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 a Ninja Foodi Smart XL Pro Air Oven in my full sized kitchen. I love this damn thing! I've often that if I lived someplace without an oven, I'd be just fine.

I have the Ninja XL whatever it is (the biggest one they make). Definitely worth getting the larger size. I cooked an entire 8 person Thanksgiving dinner without turning on my actual stove (and the turkey came out better than it does in my stove).

I have a different ninja with a built in thermometer and I'd recommend a separate one anyway. It's not that accurate

I actually just got a separate thermometer so I'm not sure yet but the separate one actually tells you the temperature. The ninja one you just set it to rare, medium,ect and I find it over cooks. I'd rather just see the actual temperature.
