I hated my old oven because it ruined my dinners. It burned my morning toast and took up too much room on my counter. I love making quick hot meals after a long day of work. Finding the right small oven felt like an impossible puzzle. I finally bought and tested two popular space-saving models. Here is how they actually cooked in my own busy kitchen.
I started with the newer and slightly bigger model first. I hoped it would solve all my nightly dinner problems.
Ninja SP351 Review
I pulled this oven out of the box on a rainy Tuesday evening. The metal frame felt very heavy and solid in my hands. The sleek silver look caught my eye right away. I wiped it down and plugged it in to make a quick dinner.
Putting the oven together took almost no time at all. I just set it down and pushed it back on the counter.
Assembly And Build Quality
I hate reading long instruction books. This oven was so simple to set up. I just pulled off the plastic tape and washed the inner pans in my sink. The metal casing feels very thick and strong. The glass door opens with a very smooth pull. The front buttons click nicely when you push them with dirty fingers.
The best part is how it flips up to lean against the wall. That clever trick frees up so much flat counter space. I love how sturdy the base stays when I push it up. I never worry about it tipping over or falling down. It stays exactly where I put it.
| Type | Feature | My Experience |
| Pro | Solid frame | The metal feels very thick and heavy. |
| Pro | Flip up | It gives me all my prep space back. |
| Con | Heavy base | It is hard to slide across the counter. |
| Pro | Smooth door | The glass door opens with one finger. |
| Con | Short cord | It barely reaches my wall plug. |
Cooking with this shiny oven has been a very fun ride. It heats up so fast I barely have time to cut my vegetables.
Daily Cooking Performance
I cook a huge batch of chicken wings every single weekend. This oven makes the skin so loud and crispy. The hot air wraps around the food perfectly from top to bottom. I barely use any cooking oil now to get a fried taste. It is also great for baking soft fish and crunchy green beans.
What I really like is the even cooking heat. I never get burnt edges on one side of my tray anymore. What I dislike is the short height inside the cooking box. You cannot fit a whole large bird or tall bread pan inside. It also gets very hot on the metal top roof. You have to be careful not to touch the top when it runs.
| Type | Feature | My Experience |
| Pro | Fast heat | Dinner is ready much faster than before. |
| Pro | Crispy crust | The hot fan gives a great loud crunch. |
| Con | Short inside | I cannot fit tall foods like whole birds. |
| Pro | Even bake | The food cooks the exact same all over. |
| Con | Hot top | I burned my finger on the metal roof once. |
Every oven has its good and bad sides to think about. Here is a quick look at the main points I noticed.
Pros and Cons
I learned a lot about this oven after using it daily. Here are the clear points that stand out to me.
| Type | Feature | My Experience |
| Pro | Quick heat | My dinner finishes cooking much faster. |
| Pro | Folding design | I get all my prep counter space back. |
| Con | Inner height | It is very hard to bake tall cakes. |
| Pro | Easy dials | It is so simple to pick a setting. |
| Con | Cleaning back | It is hard to reach inside to wipe it. |
| Pro | Bright light | I can see my food cooking clearly. |
You might wonder if this flat oven fits your daily life. I think it depends on exactly how you like to cook.
Recommendation
I looked at all the ways people cook their meals. Here is my simple advice on who will love this oven.
| User Type | Recommendation | Reason |
| Busy parents | Good Fit | It cooks quick meals very fast. |
| Big families | Not Ideal | There is not enough room inside. |
| Small kitchens | Good Fit | It flips up to clear your counter. |
| Bread bakers | Not Ideal | It is way too short for big loaves. |
| Fried food lovers | Good Fit | It makes foods very crispy. |

Then I tried the older model to see how it cooked. I wanted to see if the higher price really brings better food.
Ninja SP201 Review
I unboxed this older flat oven on a lazy Sunday morning. It looked very much like a twin to the other oven. I liked the simple and clean lines of the shiny metal body. I really wanted to see if it cooked just as well for my daily food.
Setting this oven up felt exactly the same as the first one. It was out of the box and ready to cook in five minutes.
Assembly And Build Quality
This older oven feels a bit lighter in my hands. It was much easier to lift onto the counter from the heavy box. The silver metal casing still looks and feels very nice. The back folding hinge works perfectly every time I move it. I flipped the whole oven up and down a few times just to test it.
The front buttons feel a little stiff but they still work fine. The bottom crumb tray slides out with no trouble at all. It feels like a solid cooking machine that will last a long time. I was happy with how it looked sitting next to my sink.
| Type | Feature | My Experience |
| Pro | Light frame | It is very easy to lift out of the box. |
| Pro | Smooth hinge | It flips back up with no loud noise. |
| Con | Button feel | The round buttons are a bit stiff to press. |
| Pro | Crumb tray | The tray slides out very fast and easy. |
| Con | Glass door | The door hinge feels slightly loose. |
I spent three weeks making toast and roasting veggies in this one. It handled most of my daily cooking jobs without any major fuss.
Daily Cooking Performance
I used this flat oven to make my thick morning bagels. It browns the bread perfectly with a nice soft chew inside. Roasting cut potatoes takes less time than my huge wall oven. What I liked most is how very quiet it runs while cooking. You barely hear the hot fan spin while you stand near it.
What I disliked is the raw bottom cooking heat. It can get way too dark on the bottom pan if you do not watch it. I had to flip my meat over much more often to prevent black marks. It still cooks most flat meals very well. I just had to learn to check my food sooner.
| Type | Feature | My Experience |
| Pro | Quiet fan | I can talk normally while it runs. |
| Pro | Good toast | It browns bread with perfect color. |
| Con | Hot bottom | It burns food bases if left too long. |
| Pro | Fast roast | It cooks thin sliced veggies quickly. |
| Con | Flipping food | I have to turn food over more often. |
It is important to look at the total big picture. Here are the main things I noticed after weeks of heavy use.
Pros and Cons
I found some clear wins and flaws with this model. This simple list sums up my full testing experience.
| Type | Feature | My Experience |
| Pro | Space saving | It flips away just like the newer model. |
| Pro | Simple use | The buttons are very easy to figure out. |
| Con | Uneven heat | The bottom tray gets too hot sometimes. |
| Pro | Easy clean | The drop tray catches most dry crumbs. |
| Con | Small height | It is only good for thin flat foods. |
| Pro | Quiet sound | The motor does not make loud noise. |
This cooking box is great for some folks but bad for others. Here is my honest thought on who should buy it today.
Recommendation
I thought deeply about who really needs this older oven model. Here is exactly who I think will enjoy using it the most.
| User Type | Recommendation | Reason |
| Single folks | Good Fit | It is a perfect size for a solo meal. |
| Messy cooks | Good Fit | The drop tray is very easy to wash. |
| Meat roasters | Not Ideal | It cannot fit thick cuts of raw meat. |
| Budget buyers | Good Fit | It saves money on the upfront cost. |
| Cake bakers | Not Ideal | The top heat burns high cake tops. |
This air fryer oven has everything I need to cook delicious meals quickly and easily!
Now it is time to put them directly head to head. I tested them side by side on my kitchen counter for a fair fight.
Detailed Comparison for Ninja SP201 vs SP351
Choosing a winner in the Ninja SP201 vs SP351 battle is tough. They look exactly like identical twins from the outside. I spent long weeks cooking with both to find the hidden real differences.
I wanted to see which machine cooked my dinner the best. I cooked the exact same frozen meal in both ovens at the same time.
Performance: Ninja SP201 vs SP351
The newer model packs much more cooking power. It pushes hot air around the metal box much faster. My frozen chicken wings came out way crispier in it. The older model took a little longer to give me the exact same loud crunch. I love eating food with a heavy bite.
The heat feels much more even in the newer machine. The bottom of my thin crust pizza did not burn black in it. The older oven gets a bit too hot on the bottom rack wire. Both ovens get the nightly job done fine, but one is clearly faster. I prefer the newer one for raw meats.
| Feature | Ninja SP201 | Ninja SP351 |
| Heat speed | Very good | Extremely fast |
| Air flow fan | Normal wind fan | Stronger blowing fan |
| Even bake | Bottom gets very hot | Very even heat all around |
| Crispy crust | Takes extra time | Gives perfect crunch |
| Fan noise | Very quiet | A bit louder |

I hate using home machines with deeply confusing buttons. I just want to press a green start button and walk away.
Ease of Use: Ninja SP201 vs SP351
Both cooking ovens are extremely simple to start up. You just turn the big round dial to pick your heat setting. The front screens are bright and super easy to read from far away. I think the newer model has a slightly better main menu layout. It tells you exactly what step to do next.
The older menu is fine, but it feels a bit basic and plain. The round buttons on the newer one click much nicer when pushed. They both flip up to the back wall the exact same way. It takes just one hand to fold them neatly away. They both make cooking very simple.
| Feature | Ninja SP201 | Ninja SP351 |
| Screen text | Bright green text | Clear white text |
| Push dials | Good hard feel | Very smooth click |
| Wall folding | Very easy lift | Very easy lift |
| Screen menus | Basic simple choices | More clear choices |
| Daily setup | Very fast | Very fast |

I want a kitchen oven that feels like a heavy tank. It needs to survive my daily rough and heavy use.
Build Quality: Ninja SP201 vs SP351
The metal bodies feel exactly the same on the outside. They both get quite hot on top when the fan is running hard. You have to keep extra items off the warm roof. The newer model feels slightly heavier when I lift it. The back hinge also feels stronger when you flip it up.
I clearly noticed the glass door on the newer one seals much better. Less hot air escapes out into my cool kitchen room. The older one lets a tiny bit of hot air out from the sides. Both boxes look great sitting idle on my flat counter.
| Feature | Ninja SP201 | Ninja SP351 |
| Metal frame | Strong hard metal | Strong hard metal |
| Door flat seal | Tiny air gap | Perfect tight seal |
| Back hinge | Good lift strength | Very firm strong hold |
| Heat loss | A little air escapes | Keeps hot air inside |
| Foot grips | Slides a little | Holds very firm |

Nobody likes scrubbing sticky burnt cheese off shiny metal. Cleaning a hot oven is my absolute least favorite kitchen chore.
Maintenance: Ninja SP201 vs SP351
Cleaning inside these flat ovens is super annoying. You cannot easily reach the very back wall with your hand. The flat crumb trays on both do slide out quickly from the bottom. That simple part is super easy to wash in the deep sink.
The newer model has a slightly slicker coating on the inside walls. Hot grease wipes off it much faster with a plain damp rag. The older one needs a bit more hard scrubbing with soap. You still have to flip both machines up to drop open the bottom hatch. Both ovens take real physical work to keep perfectly shiny.
| Feature | Ninja SP201 | Ninja SP351 |
| Crumb drop tray | Slides right out fast | Slides right out fast |
| Wall grease dirt | Hard to scrub off | Wipes off much faster |
| Back wall reach | Very tight fit | Very tight fit |
| Bottom flat hatch | Easy to pull open | Easy to pull open |
| Glass door wipe | Very easy | Very easy |

Buying a shiny new oven is a very big choice. I want to know if the high cash cost actually makes sense.
Value for Money: Ninja SP201 vs SP351
The older oven model saves you some solid cash right away. It does a very steady job for simple daily meals. If you just want nice toast and hot frozen snacks, it is deeply great. But the newer model simply cooks raw things so much better.
The extra blowing heat power is fully worth the higher cost to me. I cook raw thick meats and soft fish a lot. The newer oven handles those hard jobs perfectly every time. I truly think spending a bit more gets you a much better cooking tool. It feels like a massive daily upgrade.
| Feature | Ninja SP201 | Ninja SP351 |
| Upfront store cost | Much lower | A bit higher |
| Cooking speed | Normal fast | Very super fast |
| Best used for | Small thin snacks | Big full meals |
| Overall daily value | Good fair deal | Excellent top deal |
| Food quality | Good taste | Great crunchy taste |

My kitchen feels so much cleaner and happier now. This whole testing journey was very eye opening for my daily cooking.
Conclusion
Picking the winner in the Ninja SP201 vs SP351 test comes down to how much you cook. I ended up keeping the newer model for its super fast fan speed. It makes my hot dinners taste better with far less effort. If you only cook simple flat snacks, the older one works fine.
