Very Good Buy
We've been using our double stack for 3 weeks & very happy. There are a few online videos saying this model doesn't cook well or evenly. I totally disagree with this, very even cooking & on par or less cooking time than an air fryer we've had in the past. Only downside is our dog doesn't like the fairly loud bleeping!

Save your money!
I was so excited to buy this… i am terribly disappointed. It takes forever to cook anything, the holes for venting in the back of the basket make it a mess! Crumbs, oil, and juice fly out the back… truly that’s enough to hate it but there’s more… if you leave a basket open or have to open it to take food out it completely kills the heat in the other basket… the space yo...

Nice but…
Although I love all my Ninja products I unfortunately had to send this back. Yes it has dual baskets but I find them to be too small for my needs.

Needs custome togs for top tray
We like this product the xxxl double stacker apart from 2 things, the beep is SOOO loud and if you do want to move things around in the bottom tray or remove the top tray you need 2 pairs or togs or something. It should have come with custome togs to remove the tray while it's hot. This makes me not want to use the top tray anymore. Alot of money to not want to use it

Great Air Fryer!
[This review was collected as part of a promotion.] This air fryer is awesome! I love how it can hold multiple foods at once at a high volume. It’s pretty quiet too when running. Highly recommend! Would buy if I didn’t have.

Space and time saver!
[This review was collected as part of a promotion.] The Ninja Doublestack is the perfect space and time saver! From an easy lunch of nuggets and fries to extra juicy pork tenderloin medallions,baby broccoli and roasted potatoes! We have had so much fun using this at least 4 times a week in our house. The recipes are literally limitless. And it’s LARGE so you can cook ...

Love using it for everyday cooking
[This review was collected as part of a promotion.] The best thing you can do to your kitchen if you cook. Saves your time so much with double stack system. The technology is amazing. Even have a system to make your food crispier. I love the sleek design and size it fits with less space. Love using it for regular meals.

First off, I love that even though it’s XL, it takes up way less space than others of its size. It’s tall but not wide—perfect for smaller kitchens!

Great product
I got this for Christmas and I love it. My kid loves to air fryer food and with the two baskets he can make multiple meals or we can use it at the same time. The dehydrator works very well too. I made some onion powder. Very quiet I forget it’s even running.

More counter space
I’ve had several different brands of air friers some of which were Ninja. This is by far my favorite. It takes up way less space on my counter. I can cook several different foods at the same time. If the top & bottom drawer are the same, there is a button you press after you set 1 and it will set 2 for you. Cooks great.

This is something I would recommend to family
[This review was collected as part of a promotion.] It’s very easy to clean. I thought it would be a little bit bigger than it was the noise level. I gave it a five it cooks perfectly and it’s easy to use. It doesn’t take up a lot of energy.

Not Worth It
Terribly disappointed. Seems to take twice as long to cook food compared to my single Ninja. The bottom drawer is exceedingly noisy in use.

I was so impressed at how easy it was to use and how much can be cooked at once. Each chamber can even have its own settings if you are cooking multiple types of food. Clean up was a breeze!
