What’s the Ninja Prestige Smart XL?
It’s a 10‑in‑1 countertop convection oven with air‑fry, roast, bake, broil, dehydrate, and more—all housed in an impressively large but sleek stainless-steel design. It shares DNA with the DT551 Pro‑Cook model. Ninja calls it the “Prestige Smart XL” due to its smart cook probe and extra-large capacity that lets you cook multi-shelf full meals at once.

⭐ What Customers Say
👍 5‑Star Insight
“This is the LEXUS of toaster/ air fryer /counter oven… large glass front makes viewing your food super easy… The ease of choosing functions… a no brainer… It makes cooking seem like we were slumming it with our last air fryer.”
Another review: “As a vegetarian… it does an amazing job with potatoes and vegetables… replaced our full-size oven & saves on electricity.”
👎 4‑Star Reality Check
“It literally sounds like a small airplane is taking off… takes twice as long to cook or air fry vs. the Cuisinart… not worth the trade for my needs.”
- Size, performance & ease‑of‑use get glowing praise; noise is the main drawbacks
🔄 Comparison with Rivals
| Model | Capacity & Speed | Pros | Cons |
|---|---|---|---|

💷 Is It Value for Money?
Yes—if you need the size and love the multi-functionality.
- You get 10 cooking modes + smart probe + big capacity + accessories— a hefty value.
- But if you’re a small household or just want an air fryer, it’s overkill.
- And if you’re price-conscious, a standalone air fryer + toaster oven might total less.
Bottom line: it’s a premium package that justifies its pricing—if you’ll use the breadth of its features.
