It was a hectic Tuesday night. I was staring at a pile of cold frozen fries. My stomach was growling very loudly. I needed dinner fast, but my kitchen counter is tiny. This is when the big Ninja Double Stack Vs Ninja Foodi debate really hit me hard.
Ninja Double Stack Review

I bought this tall air fryer. I have zero counter space. It stacks two baskets on top of each other. This neat trick caught my eye right away.
Pros and Cons
Here is what I loved and what drove me crazy about it.
| Pros | Cons |
| Takes up very little counter room | Very tall, might hit low cabinets |
| Cooks two different foods at once | Top basket gets a bit hotter |
| Wire racks let you cook four layers | Takes longer to clean the extra racks |
Living With The Tall Stack
I have used this tall air fryer for three months. Every single day, I cook my morning bacon in it. The rich smell of crispy bacon fills the whole house. It is truly a joy to wake up to.

But pulling hot food from the top basket is tricky. I burned my wrist lightly once. You have to be careful when reaching up high. Still, it cooks food nicely once you learn its quirks.
Recommendation
This is perfect for people with tiny kitchens. If you have no counter space, get this. It is not good for folks with very low cabinets above their counters.
Ninja Foodi Review
The Foodi is a trusted friend in my kitchen. It is wide and sits heavy on the counter like a tank. I mostly use the big dual-zone model. It easily cooks a huge pile of food side by side.

Pros and Cons
Let us look at the good and bad points I found.
| Pros | Cons |
| Baskets are very wide and deep | Takes up a huge chunk of counter space |
| Easy to look into both baskets | Quite heavy to move around |
| Cooks large items very evenly | The fan noise is a bit loud |
Trusty Wide Baskets
After cooking with the Foodi for a year, I rely on it a lot. I toss whole chicken breasts inside. The wide baskets give the meat plenty of room to breathe. The skin always gets super crispy and golden.

It does hog a ton of space, though. I had to move my toaster just to make room. When it runs, the fan hums loudly. But the food comes out perfect almost every single time.
Recommendation
This machine is great for large families. It easily fits huge meals. It is not good if you live in a small space with little room.
