I love cooking outside. Bad weather always ruins my fun plans. I got so tired of cold and wet weekends spoiling my meals. I just wanted that great grilled taste inside my warm house.
Finding the right indoor grill fixed my food problems for good. I can now make tasty dinners rain or shine. It makes my busy evenings so much less stressful.
After trying a few tools, one machine quickly caught my eye for making fast meals.

Every kitchen tool has its good and bad sides, so let us look closely.

Getting this grill out of the box and onto my counter was a fun day.
My Daily Cooking And Assembly Wins
I used this machine for many months. It feels very solid and heavy on my counter. The cooking plates snap in fast and do not wiggle. Making dinner is super quick and takes no hard work. I love how my whole room smells like a real fire.
The air fan is a bit loud when it runs. It sounds just like a big hair dryer. Still, the hot food comes out great every single time. I enjoy using it a lot. It is very easy to cook my dinner and feed my hungry kids.
| Feature | What I Liked | What I Disliked |
| Box parts | Very easy to build | Lots of heavy trash |
| Power cord | Feels very safe | Too short for my wall |

Ninja DG551 Review
The newer version brought some exciting changes, along with a few minor new quirks.
Pros and Cons
| Type | Feature | My Experience |
| Pro | Smart probe | I never overcook my expensive meat now. |
| Pro | Flat grate | Wiping off the grease is very simple. |
| Con | High cost | It hurts the wallet a bit more. |
| Con | Deep menus | Pushing buttons takes more thought. |
Using this machine day after day totally changed how I planned my quick meals.
Fresh Meals And Daily Use Testing
It cooks raw food perfectly with no stress. I really love the smart meat probe. It stops me from checking and guessing the heat. I just plug it in and relax on my couch. My chicken is never dry or tough anymore. My kids actually eat all their food.
The screen is very bright and clear to see. It does take up a lot of space, though. I had to move my toaster far away to fit it. But the juicy hot food makes it worth the lost space. I use it almost every single day.
| Cooking Task | Time Taken | My Result |
| Thick steak | Ten minutes | Hot, pink, and very juicy. |
| Raw chicken | Twelve minutes | Fully cooked and safe. |
| Frozen fries | Fifteen minutes | Crisp, hot, and golden brown. |
| Fresh veggies | Eight minutes | Soft inside but firm outside. |
Figuring out if this model fits your kitchen style can save you a huge headache.
Recommendation
| User Type | Recommendation | Reason |
| Nervous cooks | Good Fit | The smart probe stops bad errors. |
| Budget buyers | Not Ideal | The starting price is quite high. |
| Daily grillers | Good Fit | Easy to clean the flat grates. |
| Simple users | Not Ideal | Screen takes time to learn well. |
This Ninja Indoor Grill does it all! Perfect for busy days when you want something quick and tasty.
Now comes the hard part, deciding which of these two machines claims the top spot.

Detailed Comparison For Ninja DG551 Vs FG551
Nothing matters more than how well the hot food actually cooks on a busy weeknight.
Performance: Ninja DG551 Vs FG551
Both grills cook food very fast. They both get hot enough to put dark marks on meat. But the newer model cooks food much more evenly. The smart probe makes a huge change for thick cuts of pork. I never undercook my big chops now.
The older model is great for thin hot burgers. For thick steaks, the newer one wins easily. It takes away all the stress of guessing. I never cut into raw meat anymore. Every single bite is warm and cooked right.
| Feature | Ninja DG551 | Ninja FG551 |
| Even heat | Very smooth and even | Can have hot spots |
| Thick meats | Cooks perfect inside | Needs hard guessing |
| Thin meats | Cooks very fast | Cooks very fast |
| Taste | Deep smoke flavor | Deep smoke flavor |

I hate struggling with confusing buttons when I am just trying to make dinner fast.
Ease Of Use: Ninja DG551 Vs FG551
The older model has basic buttons that are very simple to press. You just pick a time and heat level to start. The newer model has a smooth flat screen. The screen is nice but takes more time to learn. Using the probe means you push a few extra buttons.
Once you learn the new steps, it feels like pure magic. But for simple tasks, the older one is faster to start. I like turning a simple dial when I am tired. The new screen looks great but needs more focus from me.
| Feature | Ninja DG551 | Ninja FG551 |
| Start steps | Needs extra button pushes | Very fast and simple |
| Screen style | Flat and very modern | Basic and old style |
| Probe use | Plugs right into the front | Does not have a probe |
| Learning | Takes a few solid days | Takes just five minutes |

A kitchen tool needs to feel solid and survive being bumped around every single day.
Build Quality: Ninja DG551 Vs FG551
Both machines feel very heavy and strong. The lids stay open without falling on my hand. The older unit has a shiny finish that shows dirty fingerprints. The newer unit looks a bit more modern and sleek in the light.
The heavy cooking grates on both are very thick. Neither machine feels cheap or weak at all. I think they will both last a very long time in my home. They survive my daily cooking without a single dent or scratch.
| Feature | Ninja DG551 | Ninja FG551 |
| Outer shell | Matte and very clean | Shiny and shows prints |
| Heavy feel | Very tough and safe | Very tough and safe |
| Lid hinge | Smooth and stays open | Smooth and stays open |
| Inside parts | Thick cast metal | Thick cast metal |

Cleaning up after a big dinner is my least favorite chore, so this is huge.

Maintenance: Ninja DG551 Vs FG551
Grease goes everywhere when you grill hot meat. Both machines have deep pans that catch the wet fat. The parts from both can go in the wash tub. Warm hand washing is much better to keep them nice.
The newer model has a smooth grate shape. It is slightly easier to wipe down with a wet rag. But the smart probe needs very careful hand washing. Overall, they both take about the same time to scrub clean at night.
| Feature | Ninja DG551 | Ninja FG551 |
| Fat pan | Deep and holds oil | Deep and holds oil |
| Food grate | Flat and wipes fast | Sloped and holds stuck food |
| Lid shield | Easy to scrub | Easy to scrub |
| Total time | Ten hard minutes | Ten hard minutes |

We all want to know if the hard money spent is actually worth the results.
Value For Money: Ninja DG551 Vs FG551
The older model costs less and still gives you great food. If you just want basic grilling, it saves you hard cash. You get a lot of power for the lower price tag. It is a very safe buy for most simple homes.
The newer model costs a bit more up front. But the built-in temp probe is like having a private chef. You ruin much less expensive food. That saves real money over a long time. I think the extra cost is totally worth it.
| Feature | Ninja DG551 | Ninja FG551 |
| Base cost | Higher starting price | Lower starting price |
| Food waste | Almost none ever | Burns food sometimes |
| Long term | Saves meat costs | Great cheap start |
| Overall | Worth the high tag | Great budget pick |

Conclusion
