  • Best tool!

This Ninja DoubleStack XL Air Fryer is hands down one of the best kitchen tools I’ve ever purchased. The dual-basket design is a game changer—I can cook two different foods at the same time without mixing flavors, which saves so much time. The 10 QT capacity is perfect for family meals, and everything cooks evenly and comes out crispy every time. I’ve used it for everything from chicken and fries to veggies, and it hasn’t disappointed. The controls are easy to use, and the different cooking functions make it super versatile. Cleanup is also quick and simple, which is a huge plus.

  • This is the one you want. More expensive but this is QUALITY
Size: 10.0 Qt
This is what better than I even thought it would be. I love how it didn't have a preheat mode that takes forever like my last one. It's much more quiet than my last air fryer. It does a better job at circulating air than my last one. It gets s very even cook and I just turn the food 1-2 times. I didn't even know it had a temp probe on it. I reheated an entire rotisserie chicken on the bottom and reheated Mac and cheese on the top. The dual compartments are a game changer. The buttons are intuitive and easy to use. I love this this so much. Ninja is the best there is in my opinion. ... show more

  • Best Appliance EVER!!!
Size: 10 QT
Best kitchen appliance ever!!!!! I use this so often I have allowed it to stay on my counter. It is designed well and takes up only a small amount of real estate on the counter. I can reheat or cook a full meal. The only drawback is steak does not cook well in the air fryer but I have never had a good steak out of any brand of air fryer. Everything else chicken or fish cooks perfectly. I find that I don’t use the racks all that often but they are nice for popping in veggies last minute so they are not soggy. It was worth every penny spent. ... show more

Love, love, love this air fryer. Cooks beautifully and holds a lot. The ONLY downside is the volume of the beep which is SO LOUD with no way to adjust.

This is easy to use, instructions are clear, can fit a small chicken, relatively easy to clean, etc. It is loud though.

  • Takes up little space, and cooks great.
Size: 10 QT
Picked this up to replace an old Power XL that has the basket coating peeling off and is no longer safe to use without a replacement basket. Seems more difficult to get a basket than what it was worth so decided to just upgrade to a newer unit instead. I picked this up using Amazon card points and got it for roughly half of the normal retail thanks to said points. This is important because I don't think it's really worth the premium price outright. Originally I purchased the 8Qt version, and unfortunately one of the crisper grates that came in it had the coating peeling off right out of the box. I tried to get both Amazon and Ninja to simply send me a replacement plate, but neither one was able to do that. I had to ship the entire unit back and re-order. Since I was able to inspect the 8Qt when it came in, I decided the 10Qt would be better for the larger basket size and placed a new order for that instead. The 10Qt unit takes up virtually the same space as the 8Qt but you gain a little more basket space so it's easier to fit larger items in (chicken quarters, salmon filets, longer vegetables etc...). I'm very happy with the overall design of the unit. It vents hot air out of the side of the unit as opposed to it out the back of the unit on other air fryers, which I find as a huge positive. Our old fryer vented out the back and it completely discolored the receptacle wall plate (which would likely have caused even further issues if it had ran longer....wall paint, outlet itself, counter back splash?) So having it vent out the side where nothing is against it is much nicer (PLEASE DON'T PUT THE VENT AGAINST A WALL PEOPLE). The biggest downfall this device has, is the feedback sounds when you start up the air fryer or when it ends. Although it's nice to have a loud indication that the air fryer is done cooking, It's very obnoxious on start up with how loud the starting feedback is. This isn't a deal breaker, but Ninja really should have included a way to adjust the sound level. Others have noted that this air fryer seems to take longer to cook things, and after a handful of cooks I can attest that seems to be accurate compared to our old single bay unit that had the heat apply from the top. With that being said, I wouldn't go back....Even with it taking maybe 10-20% longer on a cook (this is around 1-10 min longer depending on what you're cooking). The unit is very good at cooking evenly if you do what you're supposed to and rotate/shake your food. Any style of cooking requires you to move the food around for even coverage, people reviewing this expecting them to be perfectly uniform heat wise at every point inside the basket don't understand how convection cooking works apparently. You wouldn't expect a burger to cook uniformly in a pan or on a flat top without flipping it....so why would you think it would be any different in a different cooking device. If you're looking to save on counter space, I would argue that this MIGHT be worth the premium. But I would more strongly encourage you to pick this up on a sale than at normal retail price. I think Ninja is being a little greedy with the price they're asking for this when it works the same as their side by side units, it's just simply rotated to be stacked as opposed to being side by side. It works great, the biggest thing to get used to would be the smaller individual basket sizes if you're coming from a single basket unit like we did (Went from a single 7Qt to dual 5Qts). I would definitely recommend giving this a shot if you're looking to save on counter space. Built quality is solid, the baskets are very easy to "toss" your food around, And it's very easy to clean. We haven't really tried out the smarter features yet where it will cooking two different things at varying temps and finish at the same time....But I'm sure that will work great based on the few cooks we've done so far. Just get your cooking times figured out and it'll become that much easier and dialed in to use. Just be ready for the loud feedback noise when you push "start" and when it ends. [FYI the feedback noise only plays when pushing start or when the unit finishes cooking, it will not make any audible noises while dialing in settings (and this is a very good thing, because if it did, then this would be a 2/5)] ... show more

  • Best dual air fryer!
Size: 10.0 Qt
I initially bought one on the Nellis site for $10 to see if I would like using and air fryer.... and I LOVE air fryers! My first one was only a single drawer, which meant I had to wash it if I needed to make veggies after meat, while the meat got cold.... so I started researching and the Ninja got really good reviews, so I bought it. It is very well made and appears durable. The baskets are super easy to clean (get the Dawn Platinum Plus Powerwash, this stuff is magic). It has very functional, easy settings, and very intuitive to use. If you hit the Smart Finish, both foods will cook and finish at the same time, which it awesome. I really love this Ninja and hope it provides many years of "air frying"! By the way, get yourself an oil sprayer (I use olive oil only). This makes it super easy to give a light coating of oil without that nasty spray junk that they sell. ... show more

  • Great for apartments!
Size: 8 QT
This air fryer is perfect if you live in an apartment with limited counter space, or you just like how it’s stacked! After months of use, it cooks evenly and has no issues with temperature or functionality. The cooking options are simple and straightforward, it is one of the best purchases we made when moving. It is decently easy to clean and automatically starts to cool itself down after it finishes cooking. It comes with a metal rack that helps separate the food and ensures a more even cook. We use this air fryer 2-3x a week, if not more, and love it. ... show more
