Head-to-head
Breville Smart Oven Pro BOV845 vs Ninja Flip SP151: Ninja folds away after cooling, Breville slow-cooks in a fixed position
The short answer
Choose Breville BOV845 for a stationary convection oven with a dedicated Slow Cook function and interior light. Choose Ninja Flip SP151 when air frying, dehydration and flipping the cooled oven upright for storage matter more. Their everyday baking overlap is broad, but the storage routine and specialist cooking modes point to different kitchens.
Before you choose
The reasoning and the trade-offs
A storage saving is not a cooking-space saving
Ninja describes a 50% reduction in occupied counter space when flipped up. The oven still has to be lowered into its working position and cooled before storage, so that benefit mainly helps counters used for other jobs between meals.
What this is based on
The manufacturer's 50% claim explicitly refers to the flipped-up position. It does not describe required operating footprint or heat clearances.
Main trade-off
Ninja Flip Toaster Oven and Air Fryer
No dedicated Slow Cook mode is listed.

What matters in practice
The differences that matter
A storage saving is not a cooking-space saving
Ninja describes a 50% reduction in occupied counter space when flipped up. The oven still has to be lowered into its working position and cooled before storage, so that benefit mainly helps counters used for other jobs between meals.
How we reached this conclusion
The manufacturer's 50% claim explicitly refers to the flipped-up position. It does not describe required operating footprint or heat clearances.
Slow cooking and dehydration lead to opposite choices
BOV845 has a documented ten-hour Slow Cook workflow, whereas SP151 lists Dehydrate and Air Fry. Someone replacing a slow cooker has a different requirement from someone drying fruit or air frying snacks.
How we reached this conclusion
Breville lists Slow Cook for up to 10 hours followed by Keep Warm. Ninja lists Air Fry and Dehydrate but no Slow Cook mode.
Air frying here changes both a mode and a supplied tool
SP151 includes an air-fry basket for its Air Fry mode. BOV845's convection fan does not mean that this selected package contains the same named setting and basket.
How we reached this conclusion
Ninja lists Air Fry and an included basket. Breville BOV845's listed modes and accessories omit both.

What you give up
Every choice has a cost
If you choose Breville Smart Oven Pro
- No dedicated Air Fry or Dehydrate mode is listed.
If you choose Ninja Flip Toaster Oven and Air Fryer
- The flip-up saving applies to storage after cooling, not the space required during cooking.
Recommendation switch
The decision flips if...
A dedicated Slow Cook workflow matters most
Choose Breville Smart Oven Pro. BOV845 documents up to ten hours followed by Keep Warm.
Air frying and storing upright matter most
Choose Ninja Flip Toaster Oven and Air Fryer. SP151 includes Air Fry and its flip-up storage design.
I need Slow Cook and Dehydrate in the same selected model
Choose neither. Neither of these two lists both functions.
What matters in practice
How to make the call
Think about the hours between cooking sessions
SP151 is attractive when the same counter also handles chopping, packing lunches or serving. Its flip-up arrangement releases space after cooling. If the oven has a permanent location and you seldom need that area back, the storage mechanism may add less value.
Choose the specialist mode that replaces another task
BOV845's Slow Cook is a concrete reason to choose it for long low-temperature recipes. SP151 supplies Air Fry and Dehydrate instead. Both bake and toast, so the functions beyond those shared basics are more likely to decide which stays useful.
Check movement and pan access
A flip-up oven needs enough room to move into and out of its storage position. A stationary oven needs room for the door and safe pan removal. Follow the installation instructions for both, and check your baking dishes rather than judging interior fit from an exterior photo.
What this comparison cannot tell you
- We have not measured cooking quality, drying performance or energy use. Ninja's stated storage-space reduction does not describe safe cooking clearance.
