I was so tired of standing over a hot stove after a long day of work. I just wanted a fast way to make a good dinner without creating a massive pile of dirty pots. That is why I started looking into indoor grills to make my evenings a little easier. I tested two popular models side by side to see which one actually gets the job done better.
Deciding on a new kitchen gadget can be super stressful. Here is how my first test went.
Ninja FG551 Review
I picked this one up hoping it would solve my weeknight dinner panic. Pulling it out of the box was super simple, and it felt heavy and solid on my counter. It does take up some space, but the sleek look made it fit right in with my other stuff.
It is always smart to know the good and the bad before spending your money. Here are my main takeaways.
Pros and Cons
| Type | Feature | My Experience |
| Pro | Fast heating | It warms up way faster than my normal oven. |
| Pro | Nice grill marks | Steaks actually look like they cooked outside. |
| Con | Short cord | I had to rearrange my toaster just to plug it in. |
| Con | Bulky size | It takes up a lot of room in my cabinet. |
Using it every single day taught me a whole lot about how it works. Here is how it handled my weekly meals.
My Everyday Cooking Experience
I have been using this model for a couple of months now. It cooks chicken breasts perfectly without drying them out. I even tried making crispy fries, and they turned out super crunchy in no time.
The only real frustration is the lid. It opens upwards and needs a lot of clearance under the cabinets. But watching a frozen steak turn into a juicy dinner in twenty minutes felt like a huge win. Cleaning the grill grate takes a bit of elbow grease if you let the grease sit overnight.
| Meal | Cooking Time | Result |
| Frozen steak | 20 minutes | Very juicy with a nice crust. |
| French fries | 12 minutes | Super crispy and hot. |
| Chicken wings | 18 minutes | Cooked all the way through perfectly. |
| Veggie skewers | 10 minutes | Soft but still had a nice bite. |
Not every gadget works for every single person. This is who I think will really love it.
Recommendation
| User Type | Recommendation | Reason |
| Beginners | Good Fit | Very simple buttons and easy to understand. |
| Big families | Not Ideal | The cooking space is a bit too small for large batches. |
| Busy workers | Good Fit | Cooks frozen food fast without thawing. |
| Small kitchens | Not Ideal | It needs a lot of counter space to open the lid. |
This indoor grill is a game-changer for cooking! Great for air frying and more.
After giving the first one a try, I wanted to see if the upgrade was actually worth it. Let us look at the second option.

Ninja IG651 Review
I was really excited to plug this one in and see if it cooked any better. It feels a bit more modern when you take it out of the plastic. The digital screen looks super sharp, and it feels just as durable as the first one.
Weighing the strong points against the weak points helps make a good choice. Here is what stood out to me.
Pros and Cons
| Type | Feature | My Experience |
| Pro | Bottom heating | The food cooks more evenly from both sides. |
| Pro | Better screen | The digital menu is very clear and easy to read. |
| Con | Heavy lid | It takes a little effort to open and close. |
| Con | Loud fan | It makes more noise than a regular fan oven. |
Testing it out for dinner showed me exactly what it can do. Here are my honest thoughts after weeks of use.
My Everyday Cooking Experience
I have used this one for a couple of months too, mostly for heavier meals. The fact that it heats from the bottom really changed how my burgers turned out. They cooked faster and tasted way more even.
I was annoyed by how loud the fan gets when it is running on high heat. It sounds almost like a hairdryer running in the kitchen. Still, the small win of not having to flip my food halfway through made me smile. It just saves so much effort when you are already tired.
| Meal | Cooking Time | Result |
| Thick burgers | 12 minutes | Cooked evenly on both sides. |
| Pork chops | 15 minutes | Very tender and not dry at all. |
| Potato wedges | 14 minutes | Golden brown and crispy on the edges. |
| Salmon skin | 10 minutes | The skin was crispy without burning the fish. |
Figuring out if this model fits your life is the most important part. Here is my advice on who should get it.
Recommendation
| User Type | Recommendation | Reason |
| Meat lovers | Good Fit | The dual heat makes steaks and burgers amazing. |
| Budget shoppers | Not Ideal | It costs more money upfront. |
| Lazy cooks | Good Fit | You do not have to flip your food as much. |
| Quiet homes | Not Ideal | The fan is quite loud during cooking. |
This grill is a game-changer for home cooks! Perfect for grilling, frying, and dehydrating.
Now comes the fun part where we put them head to head. Let us see which one wins.

Detailed Comparison for Ninja FG551 Vs IG651
Choosing between the two comes down to a few tiny details. I broke down the biggest differences based on my own testing.
Getting a good, even cook on a thick piece of meat is my top priority. Here is how they stack up.
Performance: Ninja FG551 Vs IG651
The older model cooks very well, but the heat only comes from the top. You have to flip your food to get it cooked right on both sides. It does a great job, but it requires a bit of babysitting.
The newer model has heat coming from the bottom too. This means my burgers cooked faster and I did not have to stand there and flip them. The dual heat just makes everything taste a bit more even.
| Feature | Ninja FG551 | Ninja IG651 |
| Heat source | Top only | Top and bottom |
| Need to flip food | Yes, frequently | No, cooks evenly |
| Cooking speed | Fast | Slightly faster |
| Searing ability | Good | Excellent |

Nobody wants to read a huge manual just to make dinner. Here is a look at the controls.
Ease of Use: Ninja FG551 Vs IG651
The first grill is super simple to figure out. The buttons are clear, and you can get it running in seconds. It is perfect if you just want to press a button and walk away.
The second one has a nicer digital screen. It looks fancy, but it takes a few extra clicks to get your settings right. Once you learn it, it is fine, but it has a tiny learning curve at first.
| Feature | Ninja FG551 | Ninja IG651 |
| Control style | Basic buttons | Digital display |
| Learning curve | None | Takes a few minutes |
| Screen clarity | Basic | Very bright |
| Setup time | Instant | A few clicks |

Kitchen gadgets get knocked around a lot, so they need to be tough. Here is what I noticed about their bodies.
Build Quality: Ninja FG551 Vs IG651
Both of these machines are heavy and feel like little tanks. The grates on the first one are very thick and hold heat well. The outside wipes down easily, even when I accidentally splash oil on it.
The second model feels just as strong, but the lid is noticeably heavier. Because of the extra heating stuff inside, it feels a bit bulkier. Both feel like they will last for years without breaking.
| Feature | Ninja FG551 | Ninja IG651 |
| Weight | Heavy | Very heavy |
| Lid feel | Smooth | A bit stiff |
| Outside finish | Easy to wipe | Easy to wipe |
| Grate quality | Very thick | Very thick |

Cleaning up after dinner is the worst part of the night. Here is how easy they are to wash.
Maintenance: Ninja FG551 Vs IG651
The first grill is pretty easy to clean if you do it while it is still warm. If you let the grease cool down, you will be scrubbing for a while. The parts fit nicely in the sink, which helps a lot.
The newer grill has that bottom heat plate, which adds one more thing to clean. Grease sometimes drips down there, making the cleanup process just a little bit longer. It is not terrible, but it is an extra step.
| Feature | Ninja FG551 | Ninja IG651 |
| Parts to clean | Grate and pot | Grate, pot, and bottom |
| Scrubbing effort | Low | Medium |
| Sink fit | Good | Good |
| Grease trap | Simple | A bit messy |

Everyone wants to know if they are getting what they pay for. Here is my take on the price.
Value for Money: Ninja FG551 Vs IG651
The older grill is usually cheaper and still does a fantastic job for everyday meals. If you just want to air fry and grill basics, it is worth every penny. You get a lot of power for a lower cost.
The new one costs more because of the dual heating and the nicer screen. If you cook thick steaks often, the extra money makes sense. If you just make chicken nuggets, it might be a waste of cash.
| Feature | Ninja FG551 | Ninja IG651 |
| Upfront cost | Lower | Higher |
| Best for | Basic daily meals | Thick meats and steaks |
| Long term value | High | High if used fully |
| Worth the price | Yes | Yes, for cooks |

We have covered a lot of ground today. Here are my final thoughts on the whole thing.

Conclusion
Both models are great, but the Ninja IG651 fits my cooking style a bit better because I hate flipping food. If you want a simpler machine that is easier to clean, go with the Ninja FG551. I am just really glad I finally found a way to make weeknight dinners a lot less stressful.
