Ninja SP301 Review
When I first used the Ninja SP301, I was impressed by how quickly it heated up. It has 13 cooking functions, so it’s versatile enough for almost any meal. And the flip-up design? A total game-changer for small spaces.

What I Like
- 13 Cooking Functions: This oven offers air frying, baking, roasting, and more. It’s like having multiple kitchen appliances in one.
- Flip-Up Design: You can flip the unit up when it’s not in use to free up counter space. This is especially useful in small kitchens or RVs.
- Quick Preheat: It preheats in just 60 seconds, perfect for when you’re in a hurry.
- Healthier Cooking: Air fry with up to 75% less fat! Your favorite fried foods will still come out crispy but without the guilt.
- Easy to Use: The controls are simple, so even kids can help out in the kitchen.
- Crisp Results: Dual Heat Technology helps give a nice golden edge to your food, like perfectly crispy pizza crusts.
What Could Be Better
- Durability Concerns: Some users have reported the unit stopping after a few months. This could make you worry about how long it will last.
- Customer Support: Dealing with Ninja’s warranty can be tricky. Some users have faced long wait times and high shipping costs for replacements.
- Power Cord Placement: The plug sticks out awkwardly, making it hard to place the unit flush against a wall.
- Risk of Burning: Foods like pizza or cookies might burn because of how close they are to the heating elements.
My Personal Cooking Experience
Using the Ninja SP301 has been a huge time-saver. One night, I made chicken wings, and they were crispy on the outside and juicy on the inside, using very little oil. I also roasted veggies that came out caramelized and full of flavor. What amazed me was how much quicker it cooked compared to a regular oven. Even reheating leftovers is a breeze—pizza comes out crisp, unlike the soggy results from a microwave.
Recommendation
The Ninja SP301 is perfect for small kitchens, RVs, or anyone who wants quick, healthy meals. But, if you need something durable for daily use, you might want to research other options. It’s a great appliance for light use but may not stand the test of time for heavy-duty cooking.
Ninja SP351 Review
When I first used the Ninja SP351, I noticed it was sleek and efficient. It heats up fast and delivers crispy, delicious meals. It’s a compact unit but handles larger meals well.

What I Like
- Flip-Up Design: Just like the SP301, you can flip it up to save counter space.
- Fast Preheat: Heats up in just 60 seconds, so you can start cooking right away.
- Dual Heat Technology: The 500°F SearPlate helps sear meats and bake pizzas to perfection, something the SP301 can’t match.
- Large Capacity: It holds enough food for a family meal—six chicken breasts or a 2-pound roast.
- Healthier Meals: Air frying reduces fat by up to 75%, so it’s a healthier option for your favorite fried foods.
What Could Be Better
- Durability Issues: Some users have reported the unit stops working after a few months. This raises concerns about its longevity.
- Customer Support: The warranty process is slow and can involve long wait times.
- Power Cord Design: The power cord sticks straight out, making it hard to place the unit close to the wall.
- Cleaning: Flipping the unit up can cause crumbs to fall into the back, requiring frequent cleaning.
My Personal Cooking Experience
Cooking with the SP351 has been a game-changer. One night, I seared steaks using the 500°F SearPlate, and they turned out perfectly caramelized, better than what I’d get from a grill. I’ve also baked cookies in it, and they cooked faster and more evenly than in my traditional oven. The air fryer also works wonders for reheating pizza, giving it a crispy crust, which beats microwaving any day.
Recommendation
If you want a versatile, space-saving appliance, the Ninja SP351 is a great choice. Its advanced features like Dual Heat Technology make it a winner for anyone who loves to cook but doesn’t have a lot of space. However, if durability and customer service are a priority, make sure to research further.
