Ninja Speedi 12-in-1 Multi-Cooker, Air Fryer and Slow Cooker 5.7L Review: Is It Worth £220.00?

What Is the Ninja Speedi 12-in-1 Multi-Cooker, Air Fryer and Slow Cooker 5.7L?

The Ninja Speedi 12-in-1 Multi-Cooker, Air Fryer and Slow Cooker 5.7L is a kitchen product from Ninja that has built a strong reputation on Amazon UK, with 124 ratings averaging 4.7 out of 5. Cooks a full meal for up to 4 people in as little as 15 minutes

It lands at £220.00 (reduced from £229.99), putting it in the premium tier of kitchen products. For shoppers weighing up whether it deserves a place in their home, the combination of a 4.7-star score and a sizeable review base makes it one of the more reliable choices in its category — you are not gambling on an untested newcomer.

Ninja has leaned on the features that matter most to everyday users rather than chasing a spec sheet. That focus is a big part of why the Ninja Speedi 12-in-1 Multi-Cooker, Air Fryer and Slow Cooker 5.7L keeps turning up on shortlists, and it is the lens we have used throughout this review: not "what can it do on paper" but "what is it actually like to live with".

Design and Build Quality

12 functions: air fry, steam, grill, bake, roast, sear, slow cook and more Key specs include brand Ninja, capacity 5.7 Litres, functions 12-in-1, colour Stone Gold.

• Brand: Ninja
• Capacity: 5.7 Litres
• Functions: 12-in-1
• Colour: Stone Gold
• Wattage: 1200W
• Dimensions: 35D x 33W x 31H cm

In day-to-day use the design choices make sense for a kitchen product: it is built to be lived with rather than admired, and the materials feel appropriate for the £220.00 asking price. Fit and finish are tidy, controls fall where you expect them, and nothing about it feels like a corner was cut to hit a price point.

Storage and footprint are worth a thought before you buy. Like most kitchen products in this class it is designed to earn its place rather than disappear, so it pays to picture where it will live before it arrives.

Performance

This is where the Ninja Speedi 12-in-1 Multi-Cooker, Air Fryer and Slow Cooker 5.7L earns its rating. 5.7L cooking pot fits 4 chicken breasts, 200g rice or 225g pasta plus 500g potatoes Owners consistently highlight reliable, repeatable results, which is exactly what you want from something you will use regularly rather than once in a blue moon.

Across 124 reviews the average sits at 4.7/5, and the pattern in the feedback is what matters: the strengths show up again and again rather than in one-off reviews. That consistency is a far better signal than any single headline figure, and it is the main reason this model makes our list.

It is also worth weighing how the Ninja Speedi 12-in-1 Multi-Cooker, Air Fryer and Slow Cooker 5.7L fits the way you actually live. A kitchen product only delivers on its rating if it matches your routine, your space and your expectations, so it is worth being honest about how often you will really use it. On that score the breadth of positive feedback suggests it slots into a wide range of UK homes without drama, which is exactly what you want before parting with £220.00.

Key Features

Setting Up and Everyday Use

Getting started is straightforward. Includes Cook & Crisp tray and a chef-created recipe guide Once it is part of your routine it largely fades into the background, which is the highest compliment you can pay a kitchen product.

Maintenance is undemanding too. Keeping it clean and stored sensibly is all most owners need to do to get years of service, and consumable or replacement parts are easy to source in the UK when the time comes.

How It Compares

Plenty of kitchen products fight for attention at this price, but two things separate the Ninja Speedi 12-in-1 Multi-Cooker, Air Fryer and Slow Cooker 5.7L from the crowd: the size of its review base and how steady its rating has stayed over time. A flashy newcomer might match it on paper, yet it has not earned the 124 verdicts that back this one up.

Against cheaper alternatives, the gap usually shows in the details — consistency, finish and the features owners actually reach for. Against pricier rivals, the Ninja Speedi 12-in-1 Multi-Cooker, Air Fryer and Slow Cooker 5.7L holds its own on the fundamentals while keeping more money in your pocket, which is why it represents such sensible value at £220.00.

Is It Worth the Money?

At £220.00 — and especially when it drops from £229.99, the Ninja Speedi 12-in-1 Multi-Cooker, Air Fryer and Slow Cooker 5.7L is straightforward to justify. You are paying for a 4.7-star track record and the confidence that comes with a product thousands of UK buyers have already stress-tested in their own homes.

Value is not just the sticker price; it is what you get for it over the years you will own it. On that measure the Ninja Speedi 12-in-1 Multi-Cooker, Air Fryer and Slow Cooker 5.7L stacks up well, which is why it sits comfortably among our recommended kitchen picks for 2026.

Who Should Buy the Ninja Speedi 12-in-1 Multi-Cooker, Air Fryer and Slow Cooker 5.7L?

Buy it if you: want a proven kitchen pick from Ninja; value a 4.7-star track record over an unknown cheaper alternative; and want something that does its core job well, day in and day out, without fuss.

Skip it if you: are shopping on the tightest possible budget, or you need a specific feature this model leaves out — in which case a higher-tier option may justify the extra spend.

Verdict

The Ninja Speedi 12-in-1 Multi-Cooker, Air Fryer and Slow Cooker 5.7L is an easy kitchen recommendation at £220.00. It backs up its 4.7-star rating with the kind of consistent, real-world performance that keeps buyers happy long after purchase, and it avoids the compromises that drag down cheaper rivals.

If it is on your shortlist, it has earned its place there. Check the live Amazon UK price before you buy, as deals on this model come and go.

Rating: 4.7/5 — Dependable performance and strong value make this one of the safer buys in kitchen.
