The best toaster oven I’ve ever had!
This toaster oven is the absolute best! It’s big, looks beautiful, and cooks and or reheats everything perfectly. It comes with two 12 x 12 trays that you can fit a lot of food on. I made bruschetta with baguettes and each tray held 30 pieces. It also has an air fryer tray that you can use for cooking or reheating. Everything comes out perfectly crispy. It’s very easy to use and I love that I can run both sections at once on different setting. I’m so happy with this purchase!

Great small appliance
I really love this product. It works very well and is space saving by preventing need for another small appliance and I can bake multiple items at once without having to use the larger kitchen oven. Bonus, I am impressed at how evenly this cooks!!!!

very nice works great
I bought this for my little travel trailer that has no oven. It’s pretty big for my travel trailer, but it’s very nice. Works great was a good price. It has an air fryer a roaster came with an Instructional manual. Very durable was a great buy!

great product
it's a great product, well thought out and cooks just as fast as a ninja should. I used it once with a couple of different cooking methods. it works well, I thought it was a little complicated at first. it's pretty big unit and has a lot of features. it's not just a toaster oven. I wasn't happy with the internal light, when you press the button the light comes on and pulsates and turns off in less than 10 seconds. I returned the item and I purchased a smaller, simpler ninja toaster oven

My New Go-To Oven for Literally Everything
I’ve been using the Ninja DCT451 Double Oven for a little while now, and this thing has completely changed the way I cook. I honestly didn’t expect it to replace my full-size oven as much as it has, but it heats up so fast and cooks so evenly that I end up using it for almost everything. The FlexDoor design is genius because I can open just the top section without releasing all the heat from the bottom, and it makes it way easier when I’m multitasking. The Smart Finish feature also works surprisingly well. I can put different foods in the top and bottom and have them finish at the exact same time, which is perfect for making full meals without babysitting anything. The top oven runs like a rapid convection setup, and it gets food crispy without drying it out. The bottom air fryer section is powerful, cooks quickly, and honestly does a better job than some standalone air fryers I’ve owned. The built-in thermometer has been super accurate so far, and it takes all the guesswork out of cooking meats. I’ve tried chicken breasts, steaks, salmon, and even a whole roast, and everything has come out cooked perfectly without me constantly checking on it. Clean-up is easy, the stainless steel looks great on the counter, and it doesn’t take up anywhere near as much space as I expected for something that basically acts like two ovens in one. The only thing I’d mention is that it cooks fast, so you have to get used to shorter cook times if you’re coming from a traditional oven. Once you adjust, it’s honestly a huge upgrade. This oven has become one of my favorite kitchen appliances, and I use it every single day. If you cook often or just want something fast, versatile, and reliable, this is absolutely worth getting.

Absolutely amazing! *Chef's Kiss*
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.

Great little oven plus more!
My big oven has not worked for years & I had an Oster countertop oven that worked fine however I had separate air fryer, oven. Dehydrator & the Oster broiler wasn’t great. This double oven is really cool, I am loving the features & am about ready to give up the appliances it is replacing! We air roaster a pork loin on the first use, using the attached thermometer & it was absolutely perfect! With no monitoring or attention from me which is great. The only thing I would change is adding the air fry/roast option for the top oven. One night I wanted to air roast some meat in the bottom & wanted to air fry the veggies in the top but there’s no air fry in the top. For that reason I’m keeping my air fryer but I do love this oven. Also they could have included 2 crumb trays so the (included) one doesn’t have to be moved to whichever oven that is being used. I bought an extra crumb tray from Ninja & the bamboo cutting board that fits on top, from Amazon & feel I have the best setup ever! Performance is perfect & also it cooks or heats, whatever, very fast so it saves time & also less heat in the kitchen. This is a really smart product & you will like it!

Ninja Double smart oven.
Space saving, cooks 2 different foods at different temps at once, all properly done. Easy to work with, easy to clean. All in all, I’m very satisfied.
