Double Stack XL Air Fryer, Vertical Dual Drawer AirFryer, SL400UK | with 4 cooking levels, 2 Drawers and 2 Racks, Space Saving Design, 9.5L Capacity, 6 Cooking Functions, 8 Portions, Grey

I bought the Ninja Double Stack XL Air Fryer as a Christmas present for my mother, and it ended up being used heavily over the Christmas period, including for Christmas dinner itself. Build quality is excellent. It feels solid, well finished, and like a premium appliance rather than something flimsy or gimmicky. The vertical dual-drawer design works really well and saves counter space while still offering a lot of capacity. Space is a big highlight. It comfortably handled cooking multiple items at once, which was especially useful when preparing a large meal. Being able to run different settings in each drawer makes it far more flexible than a single-basket air fryer. The controls and presets are clear and easy to use, even for someone who isn’t particularly technical. Everything heats evenly, and results were consistently good across different foods. Overall, a high-quality, very practical air fryer that’s ideal for larger households or anyone who wants to cook more than one thing at a time. My mother loves it, and after seeing it used properly, it feels like a worthwhile upgrade over smaller models.

After having an Instant Vortex air fryer that was very good, I wanted a double stack, unfortunately Instant didn't do one, so I researched and decided to buy the Ninja SL300UK. I'm pleased I chose this model, its a great compact double stack air fryer, so far I cannot fault it, The air fryer function is good and so is the roast function. im very pleased with my purchase, its great, very easy to use, time takes a little longer than and its easy to clean. I would recommend the Ninja SL300, my only criticism is the cost of Ninja air fryers. There are better build quality air fryers out there with metal handles but the question is do they cook food as well as the Ninja, probably not, this is why NINJA are a safe choice, you know the cooking experience is excellent.

The Ninja Air Fryer XL works fast and cooks food evenly with a great crispy finish. The XL size is perfect for making larger portions, and it’s super easy to use. Cleanup is quick thanks to the nonstick basket. Solid quality and definitely worth the money. Highly recommend.

Absolute beast, perfect cooking, looks great , easy to use with pre set settings

My old air fryer was perfectly fine. It cooked food, took up half the kitchen and generally got on with its life without causing any drama. Then the Ninja Double Stack arrived and immediately made it feel like I’d been cooking with Victorian technology. The first thing you notice is the design. Instead of spreading itself across the worktop like a stranded whale, it goes upwards. Whoever came up with the idea deserves some sort of national award because it somehow gives you two large cooking drawers without sacrificing half your kitchen counter space. It looks properly smart too. Sleek, modern and expensive enough that visitors assume you’ve got your life together. Little do they know you’re using it to cook dinosaur-shaped chicken nuggets and reheated pizza. The capacity is ridiculous. This thing can produce enough food for a family meal while occupying roughly the same footprint as a standard air fryer. It’s basically the TARDIS of kitchen appliances. The dual drawers are brilliant because it allows you to cook different foods at different temperatures and timings. No more trying to coordinate chips, chicken and vegetables like you’re directing air traffic control. Just throw everything in, press a few buttons and let the Ninja perform its dark arts. And somehow everything comes out crispy. I genuinely don’t understand how air fryers continue to get away with this. Chips? Crispy. Chicken? Crispy. Leftover pizza? Somehow crispier than it was when it arrived. At this point I’m fairly certain there’s a tiny wizard trapped inside. The sync function is probably my favourite feature. You can have two completely different meals cooking and the machine magically works out how to finish them at the same time. It’s like having Gordon Ramsay hidden in a drawer shouting timing instructions. The controls are easy enough to use, although like every modern appliance there are enough cooking modes to make you briefly question whether you’re operating kitchen equipment or preparing a spacecraft for launch. Cleaning is also surprisingly painless. The drawers slide out easily, the non-stick coating works well and most of the mess wipes away without requiring the strength and determination of a forensic investigator. The only downside is what happens after you buy it. You become one of those people. You start conversations with: “Have you tried it in the air fryer?” Someone mentions cooking literally anything and suddenly you’re giving a TED Talk about airflow circulation and crisping technology. Before long you’re convincing friends and family that buying a conventional oven was a mistake. You also start looking around the kitchen wondering if everything can go in it. Toast. Croissants. Wraps. Yesterday’s chips. Possibly small household furniture. Overall, the Ninja Double Stack is genuinely excellent. It saves space, cooks brilliantly, is easy to use and somehow makes weeknight dinners feel effortless. Expensive? Yes. Worth it? Let’s just say my actual oven now spends most of its time sitting in the corner wondering where it all went wrong.

We love this air fryer because it saves so much valuable space on the worktop compared to other double-drawer models. It cooks incredibly well, and the racks are very useful. The only downside we've found is that the drawers are a bit too small/narrow for larger items, so keep that in mind if you cook big portions. Overall, a fantastic, innovative product!

Nice and compact fits under worktop without taking up to much space. Easy to use.

Excellent air fryer - compact and uses the vertical space instead of the horizontal so my kitchen doesn't feel too crammed with this air fryer. The space inside feels large as well and if you need to cook more, you can use both trays at the same time.
