Game-Changer for Busy Families and Meal Preppers!
We were sad when our last Ninja Multi-Cooker malfunctioned, but this air fryer is a wonderful replacement. With the dual baskets, I can knock out reheating fries and frying wings at the same time. No juggling trays or waiting for batches. It’s built solid, heats fast, and cooks evenly every single time. The capacity is a lifesaver for family meals or Sunday prep. The controls are intuitive, cleanup is easy, and it feels like a professional-grade appliance designed for real-world households. The vertical build frees up countertop space compared to our previous air fryer. If you value time, precision, and performance, this is it. Rugged, reliable, and surprisingly sleek—it’s the kind of kitchen gear that earns counter space.

Amazing kitchen gadget!
This makes my life so much easier. So happy I decided to purchase it. Definitely worth the money. Can cook my multiple meals all in one!!! Very good quality I used it everyday and still looks great. Highly recommend for easy, quick, healthy meals. Food cooks great and taste good. Just a great product. And easy to wash with a quick scrub. Or leave it with soap and hot water!

Spacious, Easy-to-Clean Air Fryer with Innovative Double Stack Design
The Ninja SL401 Double Stack Air Fryer has been a practical addition to my kitchen. The double-stack design is very spacious, allowing me to cook more food at once, and the included rack is a thoughtful feature for dividing each basket—perfect for items like fries. I did notice that food on the rack tends to come out slightly crispier than food on the bottom plate, which works well for different textures. Cleaning is straightforward, as the racks and baskets are removable and easy to wash. The Smart Finish feature ensures that both the top and bottom baskets finish cooking at the same time, making it easy to serve multiple types of food together. This feature has resolved the issue of staggered meals I faced with my previous air fryer. While it’s not the smallest appliance, the stacked design saves counter space compared to side-by-side models and fits neatly between the countertop and cabinets. Overall, it’s a well-designed and functional air fryer for families.

Best Product – Highly Recommended!
An Essential Kitchen Upgrade – Highly Recommended! I have had an incredibly positive experience with this appliance—it has truly transformed my cooking routine! Whether it's achieving perfectly crisp toast, juicy steaks, flavorful chicken, or delicious pizza with a variety of toppings, this device excels in versatility and ease of use. The double-stack feature is a game-changer, allowing me to completely replace my oven while saving time and energy. Plus, the convenience of disposable paper molds makes cleanup effortless, making it an even more appealing choice. If you're considering purchasing one, I strongly recommend opting for the larger size to maximize functionality. This appliance seamlessly combines efficiency, simplicity, and outstanding performance—an absolute must-have for any kitchen!

Great air fryer
The two stack feature is not well explained in he instructions but, it’s not rocket science. The buttons and syncing the two cookers is also not well explained. I’ll figure it out but won’t ever get the full use of this machine just because of the thin instructions.

Ninja has done it again!
What can I say? Ninja never disappoints. I’m single so having the 10 qt is so unnecessary, but I had to have it! I got mesmerized by the capacity of roasting two 5lb whole chickens at once. One for me, one for my father. They came out soooo juicy and skin was crispy. I meal prep and I do everything at once and I’m done. It does not take up too much space on the counter or takes me all darn day to cook everything (see picture - it rests in the corner and don’t mind my empty knife block, I’m trying to save up to buy the ninja knives anyway). Anyway, I literally cook 4 different things at once because of the racks. There’s a match cook feature that can synchronize the settings to the top and bottom (ex. If you want to airfry both top and bottom at the exact same degrees and time AND a smart finish feature that times everything to be done at once, despite the different timers). Cleaning is a breeze as well because of the non stick bottom. This girl washes everything by hand cause I live in an older apartment without a dishwasher so cleaning this is easy and I don’t have to put a lot of elbow grease into it. For those that have a dishwasher, everything is dishwasher safe. There’s no weird smells of burning food or even savory smells of cooking it; everything is contained in the machine. I say it’s a durable piece of machinery and a GREAT investment. I have not even turned the oven on once since getting this. I’ve only used the air fry, roast, and reheat features. I prob will never use the dehydrator, but who knows. I have not used air broil or bake yet, but I def will! I love this machine so much! It comes with a pamphlet on times to cook things and even recipes (that I have not tried yet) Ninja hit it out of the ballpark again! (The two pictures of food was done in the ninja all at once, that’s why I’m showing them). Btw, this is my first air fryer and the functionality and versatility is unmatched by any research that I’ve done on comparing before buying.

GREAT appliance that will be well used in any kitchen!! Worth the price!
This was pricey BUT it's a versatile cooker that I've been using multiple times a week. I'm glad I went with the bigger unit with all the bells and whistles even though I live alone. I've been using the air fryer for a month or so and I just started using both baskets.....for example a protein on the bottom and 🌽 corn on the top Corn on the cob came out as the best I've ever had!!! I brushed it with olive oil before cooking and I didn't need to slather it with butter before eating-it was amazingly good! I also used the broil function this week and it was perfect compared to oven broil. I didn't have to guard it every second to make sure it didn't burn up, I set the temp and it did it's thing. I can't wait to play with the other settings like dehydrate and I want to learn how to use the function that matches cooking so both sides come out at the same time. Only complaint is the Cool function. It starts as soon as you push stop and I like my food HOT 🔥 so I have to catch it before it cools my food. I like the Cool feature just not as happy with the way it works

Double the ease....
This has been in my cart for what felt like forever! I'm so glad I purchased it! It's easy to use, cook times are easy to follow! It's not loud like some other reviews have mentioned! There is a cooling option right after air frying - I feel the taste of the food is just as good if not better than the oven. It fits right under the cabinet - I love how you can cook 4 things at once! Great for those quick meals! Or go to meals for the kids! The baskets are huge and can hold alot- I've cooked many different items in this - and have also reheated baked goods with the Bake option!
