Pros and Cons
Here is a quick look at the best and worst parts. It helps to see the facts quickly.
| Pros | Cons |
| Looks very fresh and modern | Takes up a lot of space |
| Built-in smart heat probe | Quite heavy to move around |
| Easy touch buttons on the lid | Can be loud while cooking |
Real Thoughts After Three Months
I have used this tool almost every day for three months. It makes cooking so simple. The meat always comes out juicy. I love hearing the loud sizzle when the steak hits the hot grate. It fills the room with a lovely roasted smell.

The fresh design puts controls right where you need them. It saves me from bending down. But, I did drop a raw chicken breast once while opening the heavy lid. Thankfully, the machine cleaned up fast. It truly makes weeknight meals a breeze.
Recommendation
This model is perfect for busy folks who want good meat without guessing. It is not good for tiny spaces.
Ninja FG551 Review
I bought the Ninja FG551 a bit earlier. I wanted to see what the hype was all about. It is a heavy indoor grill and air fryer. The buttons are on the front panel. It feels very strong and works like a charm.

Pros and Cons
Let us see what makes this older model shine. We will also see where it falls short.
| Pros | Cons |
| Cooks food very fast | Front buttons can catch grease |
| Huge cooking space | The lid feels a bit clunky |
| Great air crisp power | Needs a lot of top clearance |
My Experience Over A Long Time
I cooked with this model all through the winter. It gave me the joy of summer right inside my home. The smart heat probe is a life saver. I never worry about raw chicken anymore. The fries are so crunchy you can hear the snap.

Sometimes, the front buttons catch grease splatters from the meat. I spend extra time wiping them clean. Still, the smoky flavor it adds to burgers is amazing. It feels like a true friend in the kitchen.
Recommendation
This is perfect for big families who love fried food. It is not good for folks who struggle to lift heavy lids.
