This is my first air fryer, so I cannot compare this to how other air fryers work. I do have a convection oven, so I am a bit familiar with the concept. It comes with two booklets giving clear instructions for its use as well as a variety of recipe ideas for using the unit.

I like the baking pans and roasting insert as well as the wire basket it comes with, which make it possible to cook several different foods on different rack levels at the same time.

This also allows putting a baking sheet below the wire basket to catch any potential droppings from the food being air fried in the upper basket - making clean up a breeze.

The thermometer is great and easy to use, and has a very handy magnetic storage device to keep it on the side of the unit when not in use.

It quickly preheats, comes up to heat, and cooks the food without heating up the kitchen like our convection oven does. Of course, this is due to the size of this counter-top unit, but considering it is very much like a mini-sized convection oven, it is making meal prep much easier when the quantity of food doesn't require using the regular oven.

I haven't used all of its features yet, but expect them to be as easy and rewarding as the ones I have used. The food has been great. I particularly like the way the french fries are turning out compared to my simply baking them on a cookie sheet in my oven in the past.

Although I purchased this on a "door-crasher" sales event with $200 dollars off, I think it would be worth the value at the regular price now with how easy it is to use and all the features it has, notwithstanding that it takes up a little bit of counter space the smaller, but less versatile, air fryers out there. Plus, the brand is one we have always had great success with.

I love the idea of this 10-in-1 oven and air fryer, but it’s issues outweigh the benefits. It is extremely loud, it shakes & vibrates, and it gets too hot to touch. I had expected the outside to have a surface-heat protection of some sort, however, the outside surfaces is hot enough to cause injury to skin and damage to surrounding cabinets. Is it a fire hazard? Maybe, I'm not waiting around to find out. Additionally, it is huge, close to three times the size of my toaster oven, it takes up almost the entire depth of my countertop. Other than these issues, I am happy with the features, and had high hopes for an alternative, but will most likely be returning. All buttons/commands are digital, on the handle (which is odd). This could be helpful for someone who does not have an oven, if they have the space to use it safely.

I had an earlier version which I thought was subpar, especially for air frying. I read the reviews for this version, and thought "maybe they got their stuff together and this will be an upgrade." Yah, I was wrong. If you've never used a designated air fryer, then I suppose you wouldn't know what you're missing out on, and think this oven was great, and therefore the solid reviews would make sense. However, if you're like me, and have previously used a designated air fryer, you'll know the air fryer option really doesn't do well and the overall experience wasn't worth the price tag. The perks of this machine though, are that it preheats pretty fast and allows me to do other things other than air frying, which keeps my standard oven clear for bigger cooks, or not have to turn it on at all. My husband loves when I use the air roast on veggies, and you can also roast/bake bigger items than your average air fryer. I have noticed with my previous Ninja oven, that as time went on (about 8 or so months) and the oven was used more, I had to start tacking on more and more cook time to cook things I was previously cooking at shorter time lengths. So I have suspicions that this will do the same thing. I've also noticed that this machine makes the same clunks and rattles as the last. I was hoping that would be resolved with a new purchase also. I will keep it, because as mentioned I enjoy the convenience of a quick preheat, but unless they actually get this thing improved, my air fryer adventures will come from a different company.

Absolutely love this 10 in one oven. Its been a huge life saver. Its quiet and space saving. Love that their are so many cooking options between air fry, baking, reheating and dehydration. And it comes with so many different racks and roasting options. Love the internal thermometer for cooking large portions of meat to the proper temp. Love that theres a turn on light option to check on cooking status without having to open the door. The removable bottom tray makes for auper easy clean up as well. If i could give this 10 stars i would. I want to purchase one for each of my adult children. Great job Ninja providing a product (once again) that is all around fabulous.
