1) the back melted even though it was not particularly close to the wall 2) It died 14 months after we got it - just completely dead - not lights nothing - apparently a common issue

YouTube▲ recommend

Its been great!

I have this Ninja and there is a learning curve.

YouTube— neutral

I’m 50/50 on it tho mostly due to the amount of time I keep seeing it takes

Reddit▲ recommend

Bare det faktum at maden er færdig hurtigere og maskinen er 10x nemmere at rengøre gør den alle pengene værd.

Theres something on all the insides of the airfryer and I cant for the love of Jesus get it out. I tried cleaning very thoroughly, It just will not come off.

Reddit▼ don’t recommend

There's certainly no upside to the Ninja that I can really think of.

YouTube▲ recommend

Its fresken game changer for me.

Reddit— neutral

I loved it. Unfortunately, on the 18th of December, it just shit itself and won't power back up, Ninja has, however, been great, and a new one is on its way.

Reddit▼ don’t recommend

Baskets aren't firm when placed in so I guess it's defective

Reddit— neutral

We find that the food does appear to cook and tastes better than just chucking into our oven, and being dual zone means its a bit easier to cook 2 things

Reddit▲ recommend

I´d recommend the AF400, I have it myself and think it´s worth it

YouTube▲ recommend

I actually do use the dehydrator function and it works great

YouTube— neutral

the dial frequently doesn't light up so you don't know what your settings are

Reddit▼ don’t recommend

So as you can probably guess, I DO NOT recommend the Ninja.

YouTube▲ recommend

The smart finish works awesome every time for me.

r/airfryer▼ don’t recommend

I bought one of these and returned it after 1 use. It doesn't actually air fry. It took 3x the time it was supposed to to cook some frozen fries, and they still weren't crispy.

YouTube— neutral

Wish it had and easier way to get food out.

r/airfryer▼ don’t recommend

The left basket has always felt a little snug and didn't "click" in place as smooth as the right one. I can feel heat escaping, which is not the case with the other basket.

YouTube— neutral

twenty minutes it’s ready happy days.

Reddit▲ recommend

the difference is stark, it cooks stuff so much faster and crispier, having the two drawers is transformative for being able to fit loads more in, it’s quieter and so far no coating peeling.

r/airfryer— neutral

We have the dual zone. Happy with the cooking, but be gentle - if you bang the baskets around, the handles can crack. Four stars for that; not quite as sturdy as this house with a 5 year old would like.

YouTube▲ recommend

my Ninja af400 is still going strong after 2 years now

r/airfryer▼ don’t recommend

Bought mine at Costco. Turned it on. Knew it was going back in two seconds. Too loud. Wife is sensitive to noise, it was like a leaf blower.

r/airfryerⓘ good to know

Yes that's true, it's less effective when using both at the same time. You just have to learn to to adjust your cooking times accordingly.

r/airfryerⓘ good to know

I have one. Can't do a full chicken. Maybe 3-4 chicken breast per side
