I’ve been excited to share my Ninja SP151 review because this little oven surprised me. At first, I wondered if it was just another countertop gadget, but it turned out to be a real game-changer in my kitchen. From its quick preheat to its ability to handle full meals, it’s a mix of smart design and reliable performance. In this review, I’ll share what I love, what could be better, and how it fits into daily cooking. If you’ve been asking, “Is the Ninja SP151 good?” – this might help you decide.
What I Like
I’ve used the Ninja SP151 for months now, and here’s what makes it a favorite in my kitchen:
- Compact, Flip-Up Design – Saves counter space and keeps things tidy. Perfect for small kitchens.
- Versatile Cooking Options – From air frying to baking, roasting, and toasting, it covers almost everything I need.
- Fast Preheating & Cooking – Gets hot in minutes, saving me time during busy weeknights.
- Crispy & Even Results – Whether it’s fries, chicken, or pizza, the food comes out perfectly cooked every time.
- Energy Efficient – delivers comparable results to a full-size oven while using less electricity.
What Could Be Better
While I enjoy using it daily, there are a few small things that could be improved:
- Interior Height – I wish it could fit a whole chicken or larger dishes. Still great for smaller meals, though.
- Cleaning Crumbs & Grease – Some parts are easy to wipe, but crumbs collect in corners. A removable tray would make this easier.
- Toast Browning – The edges brown faster than the middle sometimes, but adjusting the rack helps.
My Personal Experience
I’ve been using the Ninja SP151 for over a year, testing it with everything from quick snacks to weekend meals. Here’s how it performed in key areas:
Design & Size
The design is sleek and modern. It feels solid, not flimsy, which I value. Its slim build saves space but still fits a good amount of food. I remember the first time I slid it under my cabinet; it fit perfectly—like it was made for my kitchen.
Cooking Capacity
I can easily fit a 12-inch pizza or six slices of toast, which works great for my family. For bigger dishes, I use my main oven, but for everyday meals, this is my go-to.
Temperature Control
The temperature accuracy is solid. I’ve rarely had to guess or adjust mid-cooking. Even when switching between air fry and bake, it holds heat well.
Basket Material
The non-stick interior makes cleanup easier, though a quick wipe after each use keeps it looking new. I avoid abrasive sponges to protect the coating
Preheating Time
It heats up in about 60 seconds, which feels like magic compared to my traditional oven. On busy evenings, this is a lifesaver.
Cooking Consistency
Results are reliable. Fries come out crisp, chicken juicy, and baked goods evenly cooked. I rarely need to rotate pans or shake baskets halfway through.
Performance
For an appliance this size, the performance is impressive. It cooks faster than I expected and handles most meals without fuss.
Ease of Use
The controls are simple. The digital display makes it easy to pick a function and set a timer, even for someone new to air frying.
Value for Money
Considering the functions it offers—air fry, bake, toast, broil—it feels like several appliances in one. I’ve saved counter space and cooking time.
Overall
If you want a compact, versatile, and reliable kitchen companion, the Ninja SP151 is a great pick. It has a few quirks, but the positives far outweigh them.
My Bittersweet Experience: Ninja SP151 Troubleshooting
Even great kitchen tools can have their off days, and my Ninja SP151 was no exception. Over months of use, I ran into a few small bumps, but each came with a quick fix that got me cooking again in no time.
Oven Not Heating Properly
Some days, the oven didn’t heat as evenly as I expected.
Problem: Food cooked slower on one side.
Solution: I learned to preheat a little longer and avoid overcrowding. A quick reset of the unit also helped restore consistent performance.
Crumb Tray Build-Up
Cleaning wasn’t hard, but crumbs collected faster than I thought.
Problem: A smoky smell during high-heat cooking.
Solution: A quick wipe after each use and a deeper clean weekly kept things fresh and safe.
Loud Fan Noise at Start-Up
The fan can sound louder than expected at first.
Problem: A slight buzzing noise when preheating.
Solution: Placing the oven on a level surface and ensuring it wasn’t touching walls reduced vibration and noise.
Alternative Option: Ninja SP101
Over the years, I’ve tested many countertop ovens in my kitchen. As someone who loves both cooking and experimenting with new appliances, I’ve found that small details often make a big difference. The Ninja SP101 has been part of my daily cooking routine, and it surprised me with how practical it is for quick meals.
Ninja SP101 vs SP151
I’ve used both the Ninja SP101 and Ninja SP151 in my kitchen. At first glance, they seem almost identical, but using them side by side shows clear differences. The SP101 feels more like the original workhorse, while the SP151 is a newer model with slight design updates.
| Feature | Ninja SP101 | Ninja SP151 |
| Dimensions | 19.7” x 7.5” x 15.1” | 19.7” x 7.6” x 14.9” |
| Weight | ~18.5 lbs | ~21 lbs |
| Interior Height | ~3” | ~3.5” (slightly taller) |
| Functions | 8 functions (Air Fry, Air Roast, Bake, Broil, Toast, Bagel, Dehydrate, Keep Warm) | 8 functions (Air Fry, Air Roast, Bake, Broil, Toast, Bagel, Dehydrate, Keep Warm, + Pizza mode) |
| Preheat Time | 60 seconds | 60 seconds |
| Control Panel | Simple, alternates time/temp display | Brighter display, more intuitive |
| Door | Basic flip-down door | Improved door design, sturdier feel |
| Price (avg.) | Usually a bit higher | Often cheaper (newer release) |
Quick Summary: The Ninja SP101 is reliable and compact, but the Ninja SP151 feels like a small upgrade with a sturdier door and slightly taller cooking space. Both are excellent, but if price matters, the SP151 usually wins.
My Final Thoughts on Ninja SP151
If you love fast meals with great taste, the Ninja SP151 is a smart choice. It works well for busy families, students, or anyone short on time. But if you cook big meals often or need more oven space, you may want to look at other options. For me, it’s been a real helper. On long days, I can get dinner done quick and still enjoy food that feels homemade.
