Instant Pot Multi-Cooker 5.7L (7-in-1, Duo-class)

This 7-in-1 is the best budget buy and the best pure pressure cooker here. It handles pressure cook, slow cook, saute, steam, yoghurt, egg/rice and keep-warm, nails the core jobs and has a small footprint that, by reviewer accounts, runs quietly - all for roughly £130 less than the Ninja OL550. Expert Reviews rates it their 'best budget option', and reviewers repeatedly cite it as 'far more affordable than the Ninja Foodi with about the same capacity' while excelling at rice and pressure cooking. The stainless inner pot resists staining (unlike Ninja's non-stick), and the whole unit stores more easily than any crisp-lid model. The catch: no air-fry or crisp, fewer functions, and a slightly steeper learning curve than Ninja's big preset menus. Note a warranty discrepancy - John Lewis lists a 2-year guarantee, while Instant Pot's own spec cites 12 months, so confirm at checkout.
