It was a dark, wet Tuesday evening. I felt a strong craving for a juicy steak. So, I walked into my cozy kitchen space. I began my deep dive into the Ninja FG551 Vs IG651 debate. Both of these machines claim to make dinner time easy. Let me share what I found during my daily taste tests.
Ninja FG551 Review

This grill is a solid choice for any home. I like how it fits nicely on my counter. It brings a lot of fun to my meal prep. You can grill, bake, and roast with pure joy.
Pros and Cons
I made a quick list of my thoughts. Here are the clear highs and lows.
| Pros | Cons |
| Cooks food very fast | Takes up some space |
| Simple to clean up | Cord is a bit short |
| Great heat control | Can be loud at times |
| Smart probe works well | Heavy to move around |
| Solid build design | Takes time to cool |
Two Months Of Sizzling Fun
After two months, I truly trust this device. It sears meat to a perfect crisp every time. The smart probe takes away all the wild guesses. I rarely burn my dinner now, which is great. It feels like magic to just press a button.

The air crisp tool is a real treat too. I use it for daily snacks and fresh sides. Sweet potato fries come out very crunchy and hot. My friends laugh at how much I talk about it. It just works well for all my basic needs.
Recommendation
This device is perfect for very busy folks. If you want fast dinners, you should get it. It saves a lot of time on week days. It is not good for tiny homes with no space. It needs a good chunk of clear counter room. It also might not suit a giant family. You can only fit so much food in it. But for a small group, it is a big win.
Ninja IG651 Review
This one is a big step up in design. It features a great flat griddle top plate. You can cook with the hood up or down. It brings a real diner feel to your home. I love making fresh pancakes on it every week.

Pros and Cons
Let us look at the good and the bad. It has some very distinct traits to note.
| Pros | Cons |
| Huge flat griddle pan | Costs a bit more cash |
| Fun hood up cooking | Takes more room to store |
| Easy and clear settings | Parts get very hot |
| Makes great fried eggs | Needs careful shelf storage |
| Top notch heat power | Quite heavy to lift |
Flipping Burgers Like A Pro
I used this flat top for many long weeks. It changed my lazy Sunday mornings for the better. Cooking bacon and eggs is so fast and fun. The flat plate gets very hot from the base. I do not have cold spots on the cooking pan.

It is quite fun to cook with the lid open. I feel like a real chef at a diner grill. The main grill grate is also quite fierce. It gives nice dark marks on my hot dogs. I smile every time I turn this unit on.
Recommendation
This model is perfect for big and hungry families. If you love breakfast foods, it is a sheer must. You can cook eggs, meat, and toast at once. It is not good for someone on a strict budget. It costs a good deal more than the first one. It also might be too big for a dorm room. You need a safe spot to keep the extra parts. If you have the space, it is a joy.
