Ninja Flip SP151 Air Fry Oven: What Reviewers Say About the Fold-Away 8-in-1

Air fryer toaster ovens all promise to replace three appliances; most of them just occupy the counter space of three appliances. Ninja’s answer is mechanical: the Flip SP151 is an 8-in-1 oven that folds up against the backsplash on a rear hinge when you are done, reclaiming roughly half its footprint. Reviewers across two generations of this design agree the flip is not a gimmick, and the current generation has real test data behind it.

As of July 23, 2026, the Ninja Flip SP151 (stainless steel) is listed at $149.94 on Amazon, 40% off its $249.99 list price.

One transparency note before the consensus: the SP151 is the current generation of Ninja’s flip-away oven. RTINGS tested this exact model. The CNET, Reviewed and TechGearLab coverage cited below tested the SP101, the first-generation version of the same flip design with a bigger chamber (nine-slice toast versus six on the SP151). We label which model each finding comes from, and design-level conclusions like the hinge, the low ceiling and the cleanup quirks apply to both.

The short version

The SP151 covers eight functions: air fry, air roast, bake, pizza, broil, toast, bagel and dehydrate, running up to 450F on a measured draw of about 1720 watts. RTINGS’ bench numbers are the story: sub-two-minute preheat, excellent temperature stability, and very even four-slice toasting. Air frying lands in the strong-for-an-oven tier, crisp and quick, just not quite the equal of a dedicated basket fryer on evenness.

The flip mechanism is the reason to pick this over the dozens of box-shaped rivals. When it is folded up, the oven occupies a strip of counter a cutting board would need, and TechGearLab found the hinge sturdy and secure in both positions on the first-generation unit.

Who this is for

The consensus profile is small kitchens, apartments, RVs and anyone whose counter space is the scarcest resource in the house. It suits households that toast, reheat, air fry sides and bake sheet-pan dinners far more often than they roast whole chickens, because whole chickens simply do not fit under the 3.3 inch usable ceiling.

The honest caveats: cleanup is the most repeated complaint across every generation of this design, since the interior is not nonstick and the exposed upper element is awkward to reach around. Toast at the full six-slice capacity comes out darker on the bottom face. And trust a thermometer or a minute of patience over the preheat beep, which RTINGS found fires early.

The deal math

At its $249.99 list price the SP151 competes with premium box ovens that out-bake it on sheer capacity. At $149.94 the calculus flips, so to speak: you are paying midrange air-fryer money for a well-reviewed 8-in-1 from a known brand plus the only storage trick in the category that actually returns counter space. If the card below still shows the discount live, small-kitchen shoppers have the easiest call here.
