Ninja Speedi 12-in-1 Multi-Cooker Air Fryer & Slow Cooker ON500UK

The appeal of the Ninja Speedi isn't the air frying — you can get that for under £60. What sets this apart is the combination of rapid cooking modes with a genuine slow cooker function in a single compact unit, meaning you can set a stew going in the morning or blast crispy wings in under 15 minutes at night without keeping two separate appliances on your worktop. For small households, that worktop space argument alone carries real weight.

Who Is This For?

This is squarely aimed at one- or two-person households who cook regularly but resent both the energy cost of a full oven and the clutter of multiple gadgets. Students in larger kitchen-share flats, young professionals batch-cooking for the week, or anyone replacing an aging slow cooker who wants more flexibility will find genuine value here. If you regularly cook for four or more people, the capacity will frustrate you — look at larger multi-cooker formats instead.

What Buyers Say

Owners of the Speedi range consistently praise how quickly it reaches temperature and the quality of the air-fry finish — noticeably crispier than basket-style budget air fryers. The slow cooker function draws strong marks for reliability and even heat. The most common gripe is the inner pot coating showing wear after several months of regular use, particularly when metal utensils are used, which is worth bearing in mind for long-term durability. The lid mechanism also divides opinion — functional, but fiddlier than it looks in the marketing.

The Deal

At £169.99 against a listed was-price of £229.99, you're looking at a £60 saving — 26% off. This product is newly tracked on our site, so we can't yet verify whether £229.99 is a genuine historic regular price or an inflated anchor figure, which means some caution is warranted.

If the price history confirms this is a real reduction, it's worth acting on — but right now, watch rather than rush.
