Build Quality
Overall Design Scoring

The design of the Instant Omni Plus 18L 140-4002-01 Air Fryer Toaster Oven shows attention to detail and makes use of modern technology, which resembles the larger Ninja DT201 a lot. While not perfect, its strong points are more than enough to make up for the minor drawbacks.

Stood out to us were the combination of one nichrome and four quartz heating elements as well as the oven’s powerful convection settings. However, the spacing between the four rack levels made it difficult to place a baking pan to catch drippings while roasting a whole chicken with the rotisserie kit.

The Ninja DT201 shows a high build quality in all of its design features from the exterior and interior to the included accessories. What stood out to us the most was the powerful convection system and the number of heating elements. We couldn’t confirm the accuracy of the Ninja’s claim that it had ‘up to ten times the convection power’ of a traditional full-size convection oven, though.

Usability Comparison

Ease of Use
Overall Usability Scoring

The Instant Omni Plus 18L 140-4002-01 Air Fryer Toaster Oven is the opposite of a simplistic analog unit like the Cuisinart TOA-60. It maximizes its ease of use but that leads to some weak points in and of itself; the same goes for its user control.

The oven’s touchscreen LCD is very easy to operate with all of its separate cooking functions and feature toggles despite having only one master-control knob and a subpar color contrast. Due to insufficient space, however, the cooking chamber can get quite tricky to clean in case of big greasy messes.

The straightforward control panel on the Ninja DT201 allowed for easy adjusting and readjusting of the cooking settings. Moreover, the informative display combined with distinguished buttons removed all of the guesswork when it came to operating the oven.

The oven’s practical cooking functions shined all the more in combination with the 2-level even cooking feature. The oven’s interior could be improved with a coating for easier cleaning, though.

Overall Performance Scoring

The performance of the Instant Omni Plus 18L 140-4002-01 Air Fryer Toaster Oven is consistently great. In particular, it’s excellent at baking/ air frying fries and roasting a whole chicken. This is thanks to its great design, strong convection system as well as useful accessories—including an air fryer basket and rotisserie kit.

The Ninja DT201 performed differently on each of our tests but even at its worst, it still gave good results. We were most impressed with the oven’s ability to quickly reach and maintain its temperature despite the large cooking chamber. This could be attributed to the oven’s high power output, powerful convection system, and a total of 5 heating elements.

With these factors, you don’t even need to turn food during cooking, especially if you incorporate the air fryer basket. Interestingly, this was one of the few units where we felt increasing the food amounts would lead to even better results.

After both going back and forth, the confrontation between the medium-sized Instant Omni Plus 18L and the large Ninja Foodie XL Pro came to a tie. Nonetheless, it was a satisfactory conclusion with both toaster ovens having their own moments to shine.

The two machines were equal in terms of interior and build quality by having more than four heating elements, interior lighting, a convection system, and a sturdy build. What gave the Instant a higher score in exterior and the edge it needs in the design department were its slide-out crumb tray and carrying handles.

Both units have similar scores in user control with their informative digital display and numerous features. However, the Ninja is significantly easier to use thanks to its wider timer and temperature range as well as its highly visible display.

The larger cooking chamber also means it’s easier to clean, not to mention the lack of nooks and crannies. As a result, the Ninja scored a returning goal in the usability department.

The most important aspect is still the performance—if the oven better cooked the food. The Ninja won it toast thanks to it having an extra rear nichrome heating element that toasted the bread more evenly. This feature also benefited the Ninja’s roasted chicken test, gaining another edge.

The Instant also has an extra top nichrome heating element but it wasn’t deployed for toasting. Nonetheless, the unit equaled the playing field with its excellent air-frying capabilities shown in the fries test.

Both units have the same power output and a convection system, so it was hard to determine the reasons why one unit was better at cooking certain food than the other. Overall, we deemed the Instant better for air frying and the Ninja for larger servings of food.
