Ninja Foodi DG551 Smart XL 6-in-1 Indoor Grill & Air Fryer

I like the grill but the only book included was the instruction booklet. There was no cookbook or cheat sheets for use. That is a big disappointment as I have to look on the internet to figure out how long to airfry things.

This is a wonderful appliance with multiple options of usage. The ultimate choice for cooking good meals.

I purchased a Ninja Grill and was very happy with it for about a year and a half—until it suddenly stopped working and began displaying an error saying the lid was not closed, even though it clearly was. What happened next was extremely concerning. We noticed a burning smell, so we opened the back housing where the lid sensor and wiring are located. The wires around the lid sensor had melted and were actually starting to burn. This wasn’t simply an appliance that stopped working after 18 months. It had become a potential fire hazard. Thank God we were home, noticed the smell, and unplugged it before it could cause a house fire. An appliance failing after a year and a half is disappointing. Finding melted and burning electrical wiring inside it is completely unacceptable and frightening. I would strongly recommend that anyone who owns this model and starts getting a false “lid not closed” error, especially accompanied by any unusual or burning smell, unplug it immediately and do not continue using it. Ninja needs to investigate this. A malfunction is one thing; a potential electrical fire is something entirely different.

For something that’s meant to be ‘smokeless’ it’s setting my fire alarms off in my kitchen. Very disappointed. And yes. I’m cleaning the filter each time. I love it but it’s just not smokeless which is why I bought it.

So far I am enjoying this product. The only suggestion I would have is I wish it had a griddle option. I don't see any attachments for that. So far it has saved me time cooking and the food has good flavor. If they were to add a griddle attachment I would give it a 5 out of 5. I would love to do pancakes on this instead of a stove top for even cooking.

I love my Ninja. I have used it alot since I brought it a couple of weeks ago.

We've used 5 times in the past week and can say we probably will never turn the oven on again! We live in an apartment where grills are not allowed. On top of that, the smokeless feature is top tier. 2 ribeye steaks, 24 large shrimp and a bunch of asparagus took 75 minutes from prep to eating. 11/10 would recommend.

I recently started using the Ninja Foodi Smart Indoor Grill & Air Fryer, and it has quickly become one of my favorite kitchen appliances. The built-in thermometer makes cooking meat foolproof, ensuring everything comes out juicy inside with a perfectly crispy finish. I really appreciate that it functions as both an indoor grill and an air fryer, saving valuable counter space. It heats up fast, runs quietly, and cleanup is a breeze thanks to the nonstick parts. Whether I’m making a quick weeknight dinner or a weekend family meal, this appliance delivers delicious results with minimal effort. I highly recommend it to anyone looking for a versatile and user-friendly cooking tool.

This is my second grill. The first one still worked after 4 years but I just wanted a newer version. I absolutely love this grill and all the features, I don’t have an outdoor grill and this one fits my needs. I also love the air fryer and the new basket is much better than the 2 provided in my old one. Temperatures are always spot on. I like my steak medium rare and they are perfect.

Let me start by saying I’m a huge fan of your products. From the grills, both outdoor and indoor, to your icecream makers, coffee makers, toaster, blenders, mixers, juicer, knives, and even vacuums, I have them all. But I started to notice the decline in the quality of your products. The leaking coffee maker, the dullness of your knives, and now the grill. When I received it, I should have contacted you directly but it is so frustrating not receiving the quality that I pay for, from a company that I love. The splash guard doesn’t stay in place. I purchased another. Still doesn’t stay in place, and it is required so the home isn’t full of smoke. I will be trying other companies from now on
