The Speedi's real trick isn't the air frying — it's the combination of steam and rapid air in a single cooking cycle. You can throw frozen chicken thighs in from scratch and have a properly cooked, crispy-skinned result in under 20 minutes without defrosting, which solves the eternal weeknight problem of forgetting to prep anything. That kind of genuine flexibility, across 12 functions including slow cooking, sauté, and rice cooking, is what separates it from a standalone air fryer sitting on your counter doing one job.

Who Is This For?

This is aimed squarely at people in one- or two-person households who are short on both counter space and time — renters, couples, students with decent budgets, or anyone trying to reduce their reliance on a full-size oven for everyday cooking. The energy saving claim (up to 55% versus a conventional oven) will genuinely matter if you cook daily. If you regularly cook for four or more people, the 6-litre capacity will frustrate you quickly, and a larger multi-cooker would serve you better.

What Buyers Say

Owners consistently praise the speed of the Speedi function itself — the combination of steam and air genuinely cuts cooking times compared to air frying alone. The intuitive dial control and easy-clean basket also get strong marks. The most common gripe is condensation management: steam cooking produces moisture that can pool around the lid and drip, which catches some users off guard and makes the worktop messier than a standard air fryer would.

The Deal

At £149.99, down from £229.99, this is an £80 saving — and the price history tells an honest story here. The lowest this unit has ever sold for is £169.99, and its average price sits around £171, meaning this £149.99 price is actually below both those marks and represents a genuine low. It won't stay there long. If the Speedi has been on your radar, this is the time to move.

Frequently Asked Questions

Yes, the ON500UK includes a dedicated slow cooker function alongside its 11 other modes, including rapid cooker, steam, air fry, bake, grill, sear, sauté, sous vide, and dehydrate. The pot capacity is 5.7 litres, which is sufficient for up to 4-6 servings. It uses a single non-stick pot throughout all functions, so there is no swapping between different inserts.

It suits households of 2-4 people who want to reduce washing-up and juggle fewer appliances, particularly those who regularly batch cook or want to air fry and steam-finish a meal in one pot using the Speedi Meals function. However, the 5.7-litre capacity will feel restrictive if you are regularly cooking for 5 or more people, and the countertop footprint is substantial — at roughly 33cm tall with the lid, it will not fit under most standard kitchen cabinets with the lid open.

Based on 56 tracked price points, the lowest this model has ever been recorded is £169.99, and the average price sits at £171.06 — meaning the current £149.99 is notably below both figures and represents the cheapest it has been in the tracked history. The original RRP is £229.99, so this is a 35% reduction and a legitimate low rather than an inflated discount against an artificial price. Buyers who have been watching this model should treat this as a strong opportunity rather than a baseline expectation.

The Instant Pot Duo Crisp (typically £130-£160) also combines pressure cooking with an air fryer lid, but the Ninja Speedi replaces pressure cooking with a rapid steam-and-crisp 'Speedi Meals' approach that is generally faster for everyday meals without the pressure-release wait time. The Duo Crisp requires swapping between two separate lids depending on the function, whereas the Ninja uses a single lid throughout, which many users find more convenient. If you specifically want pressure cooking, the Instant Pot is the better pick; if speed and simplicity of one-pot meals is the priority, the Ninja Speedi has the advantage.
