I used to smoke up my entire house every time I craved a good steak. I love grilled food, but the huge mess always ruined my dinner plans. I needed a smart tool that actually worked without setting off the loud fire alarm. Here is exactly how I fixed my daily cooking routine using these two popular machines.
Moving away from the outdoor patio changed how I cook my meals. Let me break down my honest thoughts on the first model.
Ninja FG551 Vs IG651 Review
I grabbed this model hoping for quick weeknight meals. I really just wanted a juicy burger without standing in the cold rain. It sits right on my counter and heats up incredibly fast. It feels like a little powerhouse when you turn the dial on.
Putting it together was my first big test out of the box. I am not great with tools or reading complex manuals.
Assembly And Build Quality
Taking it out of the box was super simple and fast. The parts just slide right into place with a nice click. I did not need any extra tools at all to start. The heavy top lid feels solid and safe when you close it down. The whole unit is quite bulky, so it takes up some deep space. You need a good clear spot on your counter for it. I was so happy that the main grate felt heavy and thick. It feels like it will last a really long time. My old pans warped, but this metal is very strong. I wiped it down quickly and plugged it right into the wall.
| Feature | First Impression | Build Quality |
| Main Grate | Very heavy | Solid thick metal |
| Outer Shell | Smooth dark finish | Very easy to wipe |
| Power Cord | A bit thick | Feels very safe |
| Lid Hinge | Stiff at first | Loosens up nicely |
Cooking food perfectly is the main goal for any kitchen tool. I put it to the real test with thick chicken and steaks.
Performance
This thing cooks fast. I mean really fast. I dropped a thick steak on the hot grate today. I heard that amazing loud sizzle instantly. The smart thermometer is a huge help for my daily meals. I just poke it into the raw meat and wait patiently. It tells me exactly when my food is perfectly ready to eat. I never have to guess if the chicken is raw inside anymore.
The air fry mode is also really great to have around. I tossed in some frozen fries for a quick afternoon snack. They came out super crispy in only ten minutes flat. My old gas oven took forever to do that simple job. But it does get pretty loud while it is running fast. It sounds like a strong fan blowing right in the quiet kitchen. I love how it handles the annoying thick smoke problem perfectly. My old pans always filled the living room with thick gray fog. This unit keeps the room air totally clean and very fresh. Even when I cook fatty meats, the kitchen stays clear. It gets super hot inside the main metal box. That high heat gives soft food a truly great crunchy crust.
| Food Type | Cooking Time | Result |
| Thick Steak | Ten minutes | Perfect dark crust |
| Chicken Breast | Fifteen mins | Very juicy inside |
| Frozen Fries | Ten minutes | Super crispy edges |
| Beef Burgers | Eight minutes | Evenly cooked through |
Weighing the good parts against the bad parts helps me decide. Here is what I truly loved and hated about this unit.
Pros And Cons
Looking at the big picture, this grill does a lot of things right for my daily meals. I really enjoy using it almost every day, but there are a few annoying things that bug me.
| Type | Feature | My Experience |
| Pro | Fast heating | I start cooking in under five minutes. |
| Pro | Smart probe | My expensive meat never gets dry or burnt. |
| Con | Huge footprint | It eats up all my spare counter space. |
| Con | Loud loud fan | It is hard to hear the TV playing. |
Using this machine daily taught me a lot of cool tricks. Some little moments really stand out in my busy day.
Everyday Grilling With The FG551
I use this for almost every single meal now. Making breakfast sausages is a breeze and totally mess-free for me. I love tossing in some fresh vegetables for a quick lunch side dish. It is so easy to clean the nonstick parts in the sink later.
Sometimes the digital screen is hard to read in bright morning sunlight. But I got used to it fast after a few tries. Small wins like perfectly toasted hotdog buns make me smile big. It really feels like having a personal chef right in my home. I stopped ordering expensive takeout food because cooking is so fast. My kids even ask me to grill food for them now.
| Meal | Daily Task | Frustration Level |
| Breakfast | Sausage links | Zero morning fuss |
| Lunch | Roasted veggies | Very fast and easy |
| Dinner | Thick juicy steaks | Takes some mild focus |
| Snack | Reheating cold pizza | Super quick and fun |
Deciding if this is right for you depends on your daily life. Here is who will love it the most.
Recommendation
I think this unit fits a specific type of busy home cook. If you want pure speed and pure ease, it is a huge winner.
| User Type | Recommendation | Reason |
| Busy parents | Good Fit | Cooks hard frozen food very fast. |
| Meat lovers | Good Fit | The thermometer probe is totally exact. |
| Tiny kitchens | Not Ideal | It is way too bulky to hide. |
| Quiet homes | Not Ideal | The rushing fan is quite loud. |
Elevate your cooking with this Ninja indoor grill! Perfect for all your grilling needs.
After enjoying the first one, I had to try the next model out. It looked very similar but had some fun new tricks inside.
Ninja FG551 Vs IG651 Review
I wanted to see if this upgrade was worth the extra cash. It looked a bit sleeker right out of the brown box. I really wanted to try cooking with the top lid open. That was the main reason I switched to this new machine. Here is exactly how it handled my messy morning kitchen routine.
Setting this one up felt very familiar to me right away. But I noticed a few cool changes before I even cooked.
Assembly And Build Quality
This shiny machine feels a bit more modern on my counter. The digital screen is totally flat and very smooth to touch. The metal parts are just as heavy and solid as the other one. I love the heavy new flat plate it comes with today. It feels like a thick piece of heavy iron from an old diner.
Putting the plates in and out is super smooth and fast. It snaps together nicely with a very firm click sound. I did notice the thick power cord is still a bit short. You have to keep it very close to the wall plug. But the rubber feet stick to the counter very tightly. It never slides around when I am scraping food off the plate.
| Feature | First Impression | Build Quality |
| Griddle Plate | Very smooth surface | Heavy duty cast metal |
| Screen panel | Sleek dark design | Very easy to tap |
| Base unit | Sturdy thick feet | Does not slide ever |
| Lid open | Stays up very well | Strong tight hinges |
Cooking with the lid open changed everything for my weekend mornings. Breakfast got so much easier and way more fun to make.
Performance
The open grill feature is a massive game changer for me. I love making fluffy pancakes and sunny eggs in the early morning. I can flip them freely just like on a real flat stove. The heat stays very even across the whole heavy metal plate. The outer edges get just as hot as the middle section. The smart meat probe works perfectly here too for my dinners. I cooked a thick pork chop and it was incredibly tender inside.
The air fryer part still crisps up frozen food really fast. I made spicy chicken wings that snapped loud when I bit them. I also noticed it cooks messy bacon super fast and flat. The hot fat drains away nicely into the hidden catch tray. There is far less smoke than using a normal hot pan. But it does splash hot grease a bit when the lid is open. You have to wipe the kitchen counter down after cooking greasy bacon.
| Food Type | Cooking Time | Result |
| Flat Pancakes | Four short minutes | Perfect golden brown |
| Thick Bacon | Six quick minutes | Very crispy and flat |
| Chicken Wings | Twelve total mins | Very crunchy skin |
| Pork Chops | Nine full minutes | Super juicy inside |
Finding the weak spots took a few weeks of heavy daily use. Here is what I truly loved and hated about this one.
Pros And Cons
This newer model gives you far more fun ways to cook meals. It is a blast to use, but the extra big parts can be very annoying to store.
| Type | Feature | My Experience |
| Pro | Open top cooking | I can fry fresh eggs perfectly now. |
| Pro | Flat griddle plate | Makes great toasted grilled cheese. |
| Con | Grease splashes | I have to wipe the counters much more. |
| Con | Storage space | Finding room for big parts is hard. |
Using this model every day became a super fun new routine. I fully stopped using my old gas oven completely.
Daily Cooking With The IG651
I wake up and turn this on for warm breakfast immediately. Flipping fresh hash browns with the lid up feels so natural. I do not feel trapped by a closed hot box anymore. It is great to see the real food browning as it cooks.
Washing the large flat plate is a tiny bit harder though. Hot grease tends to stick firmly in the sharp square corners. But the hot food tastes so good I really do not mind it. It adds pure joy to my busy morning routine before work. I even make fun toasted sandwiches for lunch on it now. It handles thick bread and melting cheese perfectly every single time.
| Meal | Daily Task | Frustration Level |
| Breakfast | Frying sunny eggs | Very fun and fast |
| Lunch | Hot grilled cheese | Perfectly crisp bread |
| Dinner | Smashing beef burgers | Some greasy counters |
| Snack | Toasting raw nuts | Super fast and easy |
You need to know if this fits your personal daily lifestyle. Here is my simple advice for who should buy this model.
Recommendation
If you deeply love breakfast foods, this machine is truly amazing. It does a lot more than just grill your evening steaks.
| User Type | Recommendation | Reason |
| Breakfast fans | Good Fit | The flat griddle is perfect for eggs. |
| Big families | Good Fit | You can cook a lot of food at once. |
| Lazy cleaners | Not Ideal | You have to wipe sticky counters often. |
| Budget buyers | Not Ideal | It costs much more than basic models. |

Detailed Comparison for Ninja FG551 Vs IG651
Choosing between the FG551 and the IG651 is very tough. They both changed my busy kitchen life in very big ways. Here is how they actually stack up in real everyday situations.
The way these machines heat up real food is very important. Let us look at the pure speed and heat power.
Performance: Ninja FG551 Vs IG651
Both heavy machines get blazing hot very quickly on the counter. The first model traps all the rising heat inside for super fast cooking. It acts like a tiny sealed oven that cooks thick meat perfectly. The hot air swirls around to make the food crispy fast.
The second model gives you the fun open griddle plate choice. This means you can fry wet food directly without trapping extra steam. It is much better for soft things that need to stay dry. Both units handle thick frozen food like an absolute dream.
| Feature | Ninja FG551 | Ninja IG651 |
| Heat style | Fully closed box | Open or closed top |

I do not like complex digital buttons or confusing bright screens. Simple and fast is always way better for my tired brain.
Ease of Use: Ninja FG551 Vs IG651
The physical buttons on the first machine are big and easy to press. You just pick your target heat and quickly hit the start button. The smart meat probe setup is foolproof and guides you right perfectly. It beeps loud so you never ever ruin a nice expensive meal.
The newer machine has a sleeker spinning dial and a shiny flat screen. It takes a full day to learn the fancy new menu layout. But cooking with the top lid open is very natural for me. It feels just like using a normal flat stove pan at home.
| Feature | Ninja FG551 | Ninja IG651 |
| Control type | Big physical buttons | Sleek spinning dial |
| Screen look | Basic digital numbers | Modern shiny flat look |
| Probe use | Very easy setup | Very easy setup |

A good expensive kitchen tool needs to survive heavy daily use. I want something tough that will never ever easily break apart.
Build Quality: Ninja FG551 Vs IG651
Both metal units feel like heavy tough tanks on the kitchen counter. The cooking grates do not bend or warp even at the highest heat settings. The top lids feel heavy and stay exactly where you leave them up. The strong hinges never wobble when you open them very fast.
The sleek finish on both is very smooth and wipes down easily. I did notice the newer model looks slightly more premium and shiny. But they both seem fully built to last for many years of daily dinners. They are tough blocks of strong metal and thick hard plastic.
| Feature | Ninja FG551 | Ninja IG651 |
| Total Weight | Very heavy | Very heavy |
| Lid hinge | Strong and tight | Stays open very safely |
| Outer shell | Hard dark plastic | Premium gloss finish |
| Grate metal | Thick heavy metal | Thick heavy metal |

Nobody wants to scrub greasy metal pans all night long. Fast cleaning up matters a whole lot to my daily peace.
Maintenance: Ninja FG551 Vs IG651
Washing the dirty parts for the first grill is super fast. I just throw the warm grate in the sink and scrub gently. The smooth nonstick coat does almost all of the hard work. The inside of the top lid just needs a fast wet wipe.
The second flat grill makes a bit more messy grease outside the box. Because you cook with the lid up, the flying grease hits the counter. The wide flat griddle also traps tiny bits of hard food in the sharp corners. You have to scrub a bit harder to get it fully clean.
| Feature | Ninja FG551 | Ninja IG651 |
| Grate cleaning | Very fast wash | A bit sticky inside |
| Counter mess | None at all | Frequent oil splashes |
| Splash shield | Easy to wash clean | Easy to wash clean |
| Time to clean | Five short minutes | Ten longer minutes |

Spending good money on new kitchen gear is a big serious deal. You want your hard cash to work very hard for you.
Value for Money: Ninja FG551 Vs IG651
The older solid machine is usually much cheaper to buy today. If you just want to grill thick meat indoors, it is an amazing deal. It saves so much money on expensive takeout food really fast. You get perfect juicy steaks for a very low starting price.
The newer shiny model costs more cash but gives you a full griddle experience. If you make flat pancakes and smash burgers a lot, the extra cash is worth it. It fully replaces several other rusty pans in my busy house. You get two totally different cooking styles in one single machine.
| Feature | Ninja FG551 | Ninja IG651 |
| Upfront cost | Much lower price | Higher premium price |
| Core features | Basic indoor grill | Grill and full griddle |
| Best use case | Fast meat dinners | All daily fun meals |
| Worth the cash | Yes absolutely | Yes absolutely |

Ninja IG651 Rating: 8/10
Bringing it all together shows a very clear winning picture. Here is my honest final thought on this big showdown.
Conclusion
Both of these powerful machines totally changed how I feed myself every single day. The first model is absolutely perfect if you just want fast, easy dinners with zero mess. I reach for the second one when I want a huge fun weekend breakfast with open frying. Pick the tough machine that best fits how you actually love to cook your food.
