    I’ve had this air fryer for quite a few months now and use it almost every day

    It fits nicely under the cupboards on the work top and is slim so it takes up very little room

    Anything you can do in a conventional oven or under a grill you can do in this air fryer. There are only two adults in our household and this air fryer is perfectly adequate for us. It claims to be able to cook enough food for 4-6 people. I think the maximum would be 4 but Ninja do make a bigger double stack so if your household is bigger you might want to consider the bigger one.

    It has two “zones” that work independently of each other so you can cook two different items at different temperatures at the same time. The sync function is very handy so both items will be done at the same time. Each zone has two positions – upper and lower – so as long as the two foods cook at the same temperature you can do them both in the same zone.

    It has different cooking methods
    Air fryer
    Max crisp
    Bake
    Roast
    Reheat
    Dehydrate

    Each one has a default temperature and cooking times but all of these, with the exception of Max crisp, can be altered.

    I have barely used my gas oven since I got this air fryer and will more than likely get rid of my old cooker and just get a gas hob.

    If you like baking it works well for that too. I don’t do a huge amount of baking but have made a sponge cake and scones which came out well. One thing to remember though is that both zones are quite small (just over 6 inches/15cm) so you might find your existing baking tins won’t fit in this.

    I’ve done a roast dinner in it and the chicken and roast potatoes came out really well. Again with its narrow design the maximum size chicken that will fit in it is 1.2 kg

    The instruction book is very good and comprehensive. It gives suggested temperatures and cooking times for most things and I’ve found these to be pretty accurate.

    It’s easy to clean but I would suggest buying some paper liners to help keep the basket clean.

    All in all a really good air fryer at a reasonable price

    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.

    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.

    Fantastic piece of kit. I think it may be my new best friend. Managed to fit a 1.6kg chicken in one drawer and veggies for 2 in the other. My oven may well become redundant.

  6. Wainy

    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.

    Brilliant air fryer, couldn’t be without it. Looks great too

  11. Kaspars Melnis

    This is my second air fry, and this one is pretty good. It has two containers and I can air fry extra food. Times when I need to air fry smaller portions like a 3 piece chicken wing I can select a rack to use. I love how well it cooks foods especially the interior, it’s just so well done. When it comes to cleaning, it’s easily detached and can be soaked in water and of course must be completely dry before use. This air fryer is a no brainer and is really easy to use just like any air fry. I spent extra money for a bigger version of an air fryer and I love how well it’s made using a high quality type of plastic for the exterior with a grey matte finish making it feel premium.

  12. Ooi Sheah

    The best thing I’ve bought in ages. Saves me so much time and effort. No more burning things in the oven as once the timer goes off it stops. The two sections means I can cook multiple foods in one go and the dividers means you can cook even more. Great value, great quality item, reduces the need for oil so less to worry about.
