What the retailer listing confirms
AO currently lists the Ninja Foodi MAX 15-in-1 SmartLid OL750UK_BSS at £302, with an AO member price of £286. The page shows a 4.9/5 customer rating from 285 reviews, while the tracked product data also shows a 4.7 rating details from up to 2,022 reviews. Key listed details include 7.5 litres, 15 cooking functions, 1760 watts, Stainless Steel, rotary control, a display, a grill, a non-stick finish and an on/off switch.
What the wider review context suggests
The clearest public theme around this Ninja model is that the 7.5-litre pot and broad function set are aimed at larger recipes, batch cooking and shoppers who want one appliance to cover several jobs. TechRadar’s coverage is positive overall and also notes the automatic steam release, built-in temperature probe and dishwasher-safe accessories, but its review is older and size is part of the trade-off. Which? offers useful Ninja and multi-cooker context, but the accessible pages do not show a product-specific verdict for this exact model, so retailer review sentiment should be treated as support rather than proof.
The main trade-off before you buy
This model’s appeal is flexibility: 15 cooking functions, air fry and steam roast modes, and a larger 7.5-litre capacity make it attractive if you cook for several people or like batch prep. The trade-off is that the premium £302 price and bigger footprint only make sense if you will actually use those extras often; simpler and cheaper multi-cookers will be better value for smaller households, lighter cooking needs or buyers who do not want to pay for features that may stay unused.
Price and value benchmark
At £302, the Ninja Foodi MAX sits well above the peer median of £60 in the tracked comparison set, so it is not a budget buy. The £286 AO member price helps a little, but value still depends on whether the 7.5-litre capacity, 15 functions and extra features will replace other appliances or just duplicate them. If you only want a straightforward multi-cooker, there are many lower-priced alternatives to compare before committing.
How it compares with nearby alternatives
Against smaller rivals such as the Ninja Foodi OP350UK 6 Litre Multi Cooker and the Ninja Foodi 11-in-1 SmartLid OL550UK 6 Litre Multi Cooker With Air Fryer Function, the OL750UK gives you more capacity and a wider 15-function spread. TechRadar also highlights automatic steam release, a temperature probe and dishwasher-safe accessories, which make it feel more complete than simpler models. That said, the extra capability comes with more cost, so the key comparison is whether the larger pot and broader feature set match your everyday cooking habits.
How much trust to place in the review scores
The AO page’s 4.9/5 from 285 reviews is reassuring, and the tracked rating details of 4.7 from up to 2,022 reviews suggests broad public approval. Even so, retailer-hosted reviews are not the same as independent performance assessment, and TechRadar’s positive coverage is older rather than a fresh market check. The safe reading is that sentiment looks strong, but you should still verify the live listing, price and specs before buying.
Who it suits
This Ninja should suit bigger households, batch cooks and shoppers who want one appliance to handle several tasks without switching between multiple devices. The 7.5-litre capacity is the standout reason to consider it, and the 15 cooking functions make more sense if you regularly use air fry, steam roast and other modes rather than just one or two settings. It is also a better fit if you prefer a premium, all-in-one appliance rather than a basic cooker.
Who should look elsewhere
If you have limited counter or cupboard space, the OL750UK may be too large a commitment, especially once you factor in storage and daily handling. Budget-conscious buyers may also find the £302 asking price hard to justify when simpler multi-cookers cost far less. If you only need occasional cooking help or one main function, the extra modes may be more than you need.
Fit, footprint and everyday use
TechRadar reports the SmartLid model at 36 x 35 x 36 cm, so worktop space and cupboard clearance matter just as much as capacity. The 7.5-litre pot is useful for larger meals, but the physical size means it is worth checking where it will live in your kitchen before you buy. Features such as rotary control, a display and dishwasher-safe accessories should make day-to-day use easier, but only if the appliance fits your routine and storage space. For smaller kitchens or solo cooks, that larger footprint may feel unnecessary unless you regularly make bigger portions.
Value judgement
The Ninja Foodi MAX 15-in-1 SmartLid is a shortlist item if you want a useful feature set, a bigger pot and a premium multi-cooker from a brand with strong public review sentiment. It is weaker value if the £302 price is mostly paying for functions you will not use, or if the 36 x 35 x 36 cm footprint is awkward for your kitchen. Check the latest AO price and availability, then compare it with simpler and cheaper cookers before deciding.

Questions about this electrical
Is the Ninja Foodi MAX 15-in-1 SmartLid worth it for a family or batch cooking?
It looks most compelling for bigger households and batch cooks because of the 7.5-litre capacity and 15 cooking functions. If you regularly cook larger portions or want one appliance to cover several tasks, the premium price is easier to justify than if you only need a basic cooker.
How much counter or storage space does the SmartLid need?
TechRadar reports dimensions of 36 x 35 x 36 cm, so you should check both worktop space and cupboard clearance before buying. That footprint is manageable in some kitchens, but it is still a meaningful size if you plan to store it away between uses.
Are the 4.9/5 and 285 reviews enough to trust it?
They are a positive signal, but they are not the same as independent performance testing. Treat them as a useful reputation check, then also compare the price, size and features against simpler multi-cookers before you buy.
What do the 15 functions add over a simpler multi-cooker?
The extra functions widen what the appliance can cover, including air fry and steam roast modes, so it can replace more than one kitchen device. That is helpful if you cook varied meals often, but less useful if you only need a couple of core settings.
Is this a good buy if I mainly want air frying?
It can work if you also want the larger 7.5-litre pot and extra multi-cooker functions, but it is probably more appliance than you need for air frying alone. In that case, a simpler and cheaper air fryer or smaller cooker may be better value.
