After owning a Ninja Foodi Indoor Grill for about 2 years, which heated up to 450 F but that I almost always used at 400 F, I must say that this air fryer does not heat up to 390 F. In my experience, it takes at least 50% more time than my previous Ninja air fryer to cook the same food.
Also it is small and flimsy, extremely flimsy, it feels cheap (it is cheap), although for the price, it is fair (as it also costs 1/3 of the Ninja Foodi)
PROS: it looks cute and the “glass” window is very convenient (plastic window of course)
Conclusion: Very weak and small, not practical and not worth the hassle. It takes for ever to cook the food and forget cooking meat as it doesn’t sear the meat properly sue to the week temperature.
