Ninja appliances are among the top priority of most users, and they receive high ratings from customers. Same in the Ninja AG400, with 4.8 stars rating on Amazon, the AG400 ninja Foodi machine is among the highest-rated indoor grills.

Starting from the design, the Ninja is built with high-quality materials. Customers said about using it for more than two years without any issue. Operating and navigation are user-friendly, and the digital controls are easy to read.

Despite a full-time indoor grill, its other functions pleased the users. It is even better than some of the expensive Ninja foodi digital air fryer oven in the market. The grilling is nearly smokeless, even when I tried cooking thick steaks.

The smart temperature probe does a wonderful job at controlling meat cooking. It lets users select the level of doneness. But, it won’t be at the level of control you get with the new models.

But, AG400 isn’t suitable for all the users. Firstly, the machine is large for most countertops. On top of that, it’s quite an expensive machine (above $250). Anyways, there are a few drawbacks you won’t like to overlook. You will need to wait for some time after switching on the machine to preheat.

If you care about grilling quality, then money, and space, it’s one of the best indoor grills.
