"It's MUCH easier to clean non stick surfaces (1 minute after each use). ... Takes me 1 minute to clean my Cosori with a nylon brush and Dawn."
"Clean up is a snap all it takes is a little bit of your dish detergent I use Dawn and three tablespoons of baking soda made into a small little paste you cover the inside you cover the. Inside in the rack with it you wait 15 minutes rinse it well with warm water paper towel dry it and it's done."
"both baskets go in the dishwasher, which makes cleanup way easier"

"and I absolutely love being able to cook two different things and match their cook time."
"The dual baskets let me cook two things at once (like chicken wings in one and fries in the other) with different settings, and they finish at the same time thanks to the “Smart Finish” tech."
"a "smart finish" setting so they finish together"

"My favourite thing to cook in my dual Ninja air fryer is a roast chicken. I split it in half and, cook it for about 35/40 minutes and it ’s the best roast chicken I’ve ever had."
"I like my Ninja oven and air fryer combo for its versatility ... plus the results I'm getting on everything coming out of it are outstanding imo. ... Roasted a whole stuffed chicken last week as well as cooking scratch made pizza. Outstanding!!"
"I use it everyday and my cooker is redundant."

"I have to lower a lot of my temps or reduce cooking time comparatively to my oven, so 400 is more than enough for everything I’ve done."

toaster over + air fryer combo I really like the ninja sp351, bought it 2-2.5 years ago and it’s holding up well. Toasts, air frys, and the griddle works pretty great to cook in for quick meals / reheating / roasting ingredients while the main over is busy Unless you cook a lot of premade frozen food, that’ll be far more useful than a microwave
A combo unit, like [13-in-1 Ninja appliance air fries, sears, bakes with 75% less fat than deep frying, fast and versatile healthy cooking](https://a.co/d/gWhBCZL). If you can only have two, I recommend something like this and a microwave. If only one, honestly I think this is more versatile than a microwave and makes better food in general. This is the model my parents have, not sure if there is something else out there more suited to your needs but I've done a lot of different meals in this thing (toasting, reheating, searing, oven, air frying, etc) and to my knowledge it truly does work well at the different cooking types it claims (again have tested/tried everything, just the more normal stuff and have enjoyed using it). The benefit of this particular one is that it has a pivot stand, so you can fold it up out of the way when not in use to reclaim some of your counter space. My dad likes to leave it up and I like to leave it down cuz I constantly have to clear clutter away to fold it down. I've compared making roasted vegetables in the oven and in this machine and I tend to prefer this machine over the oven. Plus if you're cooking for only one or two, the size is about right for it and not too hard to clean (unlike having to try to clean the whole glass stove stop, not hard just a lot more surface area). I don't mean for this to sound like an ad, like I said this is the one I have and I like it. There are likely other versions of this same style (a combo unit designed to be multiple machines in one). Likely a good version of each machine would perform better in its specific category, but a combo unit like this achieves I think 90% of the same result or sometimes better in rare cases, but has the benefit of less room being taken up since it's one machine, and it can be folded up for more counter space. When I get my own place, I am planning to either get myself this one, or look at what is available and try to find something even better if it's an option, and won't worry about other appliances until I actually need them (cuz this does pretty well by itself).
I have the Ninja 12-in-one. I use the regular oven when whatever I’m cooking is too big for the ninja.
I have a different ninja with a built in thermometer and I'd recommend a separate one anyway. It's not that accurate
I actually just got a separate thermometer so I'm not sure yet but the separate one actually tells you the temperature. The ninja one you just set it to rare, medium,ect and I find it over cooks. I'd rather just see the actual temperature.
I have the Ninja Foodie oven one. I figured out some liners that solved the cleanup issue, and it’s my go to for cooking a big batch of chicken breasts.
The third one in the list, the Ninja Air Fry Oven, was terrible for me. So much grease would get everywhere even when using the drip pan. I went to the first one in the list, the bucket style Ninja, and it’s so much better.
I like my Ninja oven and air fryer combo for its versatility and speed of cooking - plus the results I'm getting on everything coming out of it are outstanding imo. Roasted a whole stuffed chicken last week as well as cooking scratch made pizza. Outstanding!!
So I have two air fryers. Both are ninjas. One is single and one is dual. I do agree the single is better. It's really convenient to have three air fryers when making something like air fryer chicken, roasted veggies & fresh french fries. I can make all three at the same time and eat at the same time. Super convenient. Also if making wontons and spring rolls. I have a pretty busy job, a young child & a husband who doesn't cook. So for me worth it to have all. I also have enough space in my kitchen.
Yup I did a post on mine several months ago. Definitely takes more time when cooking with both sides and it can be hard to figure out timing. I wish I stuck with my single one.
I just mean in the sense that it cooks a lot slower using both sides vs one so have to figure out timing for stuff to be done. It isn't the usual times I would set when using just one side. Apparently this is an issue in the US due to voltage from what I was told numerous times on my last post. Just wish I knew before I got it. If you're in the US and this one takes just as long when you use both sides, you're lucky I guess. 🤷♀️ i have much longer cook times using both sides than I do with one, or with my one basket ninja I used to have.
Have a Pampered Chef and a Ninja dual , the ninja is useful for cooking two different things but the Pampered Chef just outperforms the ninja in every way! We use it 3-4 times a week and have had it for 5-6 years.
