We've had other countertop oven/air fryers and used them daily. This Ninja double oven is by far the best. Having two ovens in one is remarkably efficient and makes meal production faster and easier. You can do steak in one, fries in the other, or a meal for adults in one, and different items for the kids in the other, or an entree in one and a dessert in the other. This appliance is well built, well thought out, and the learning curve on the controls is short.... but it's there, especially regarding use of the thermometer. The internal food temperature thermometer is a big plus when you correctly use it. We are thrilled with this double oven and have fun using it every day. Only downsides are it's a bit noisy (a minor issue), a bit larger than traditional toaster ovens, and the large sheet pans and air fryer basket are supposed to be washed by hand, so cleanup is a bit of a chore. All in all, however, we would buy this again in a minute!

This oven has quickly become my favorite kitchen appliance, and it's made cooking an absolute joy.Size: The size is one of the things I love most about this oven. I looked at like 6 countertop ovens and this is the biggest I could find. To give you an idea, it can fit two whole chickens in the bottom and around 12 hot dog buns at the top.Ease of Use: How easy is it to use? I don't know if it could be any easier. Whether I’m toasting bread or baking a pizza, the controls are easy. For toast, you just choose how many slices and the toasting level you want. For pizza, it’s just one button and start, and it even preheats automatically. It really couldn’t be simpler. Also as for cleaning, I haven't had issues there, the removable attachments makes cleaning easier.Noise Level: The noise level is insanely low. The top section is so quiet that sometimes I have to check if it’s even on! And yep, it's definitely on. The bottom section is louder, but it’s still quieter than I expected.Attachments: It comes with all the necessary trays, baskets, and even a thermometer if you get that version. The only thing I wish it had was an extra crumb tray. It only comes with one, which I don't really understand.Food Results: The most important part. As you can see in the pictures, it has giving me great food results. Whole chickens come out juicy and with great color, pizzas are delicious and with no flop, and chocalate chip cookie were soft with melted chocolate. The only slight issue I’ve had so far is with roasted potatoes, they weren’t really crispy, but I might just need to cook them a bit longer.Build Quality and Design: As with other Ninja products, the build quality is excellent. I’m confident it will last a long time. Plus, it looks great in the kitchen, it's very nice to look at and it modernizes the kitchen.Overall: I’m really happy with this purchase. I’d definitely recommend it.

The size is very good. Having 2 ovens in-one is a plus. Air-fry works great.Have been using it for several months now and found that toasting takes longer than it did in the first few weeks. Very noticeable difference.Two negatives:1. There is a cooling fan that runs after the oven stops (for ALL functions). It runs insanely long and does not seem to serve any purpose. Nor is it detecting the temp. Tested this by unplugging and plugging back in. The fan did not kick back on, so it must be on a fixed timer. All products have a "mean time before failure (MTBF)". My theory is the cooling fan will wear out far sooner than it should and might render the oven useless. So I've put the oven on a short power strip to cut power and stop the fan from running. No toaster oven (or toaster) I've ever had over many decades has every had a post-op cooling fan.2. The lower oven does not have a broiler element. You can only broil in the top oven. Not terrible, but did not expect that.It does otherwise operate very well. The outside skin stays remarkable cool when cooking. There is a "slight" bleed-thru of heat from the lower to the upper oven, but doubt it's enough to have any real effect on top-baking time/temp.
