Customer reviews

So far so good
I read the reviews before purchasing and everyone is correct about the thermometer not working, but I have noticed that if you follow the cooking temps and times that are recommended everything cooks very well. So far I have air fried pork chops, I have air fried homemade potato wedges and I grilled a few pieces of chicken. Everything came out really good. I was especially impressed by how well it cooked the meats. The pork just melted in your mouth and the chicken was juicy and delicious. The potato wedges were crispy and cooked perfectly with the recommended time and temp. I have seen a lot of reviews saying it's not a smokeless cooking experience but if you read the instructions it clearly states you should not use cooking oils such as olive oil or vegetable oil for a smokeless cooking experience. I tested it out by coating the pork and the chicken, very lightly (tossing them in a bowl) with olive oil and I had a smokeless cooking experience. So I assume people are just using too much oil if they are getting a lot of smoke. The machine it's self is slightly smaller than my small microwave, so it was a little bigger then I expected. I would say it's easy to use when the instructions are read properly. I've always had trouble cooking meats on the stove top, they never come out perfectly. I would recommend this for air frying and grilling especially if you're someone who is not particularly good at cooking meat. Update: I have been using the machine for a few months now and I had noticed anything, like meat that is very greasy will make the grill smoke heavily. I recommend cleaning the top circular smoke screen after every use for a smokeless experience. It is hard enough to clean after one use but I have noticed that they sell extra smoke screens on here so they can easily be replaced if not cleaned. I have also seen inserts for the bottom pan that I'm seriously considering purchasing because if you don't have a dishwasher cleaning this machine after use is a bit of a chore. I also recommend using the grill brush that was included. Trying to use a regular sponge on the grill makes it nearly impossible to clean properly. The grill brush makes it so much easier.

Love my Ninja grill
I'm not a big fan of gimmicky kitchen appliances and don't fall for the hype of the newest and best gadgets. I try to minimize waste of money and space, not to mention time. I tried a ninja air fryer after being talked into it by a friend and hated it. I mostly eat a lot of meat and generally like moist meat, fat in tact. I never cook fries or frozen foods. I returned that and started thinking about my diet and what is practical. I really liked the versatility of this grill having so many functions. Yes, it does have an air fry function. I grill out a lot and decided this would be less messy, less time consuming and obviously less dependent on weather. I eat a lot of steak, burgers and chicken. This seemed perfect. My daughter does eat frozen foods and bakes so i knew she'd use it also. Plus it's 90 + degrees here right now so being able to keep the oven off is great. I've used this so many times already. Steak, chicken, burgers, muffins, toasted bread. It's amazing. The preset function with the thermometer works very well. You have to trust it as it cuts off a bit early but there is a carry and rest time on the meat. Burgers perfect medium every time.snd super fast without the greasy mess of frying open skillet. And it looked huge on the website but doesn't take up nearly as much space as I thought. Super easy to clean. This is an appliance that will not be thrown in the back of the pantry. Love this grill

This is my new favorite kitchen utility!
I have used this only a short time, but the unit is well made with nothing easy to chip and with apparently ceramic coated pan, basket and grill plates which are all dishwasher safe. I have seen it warm impressively quickly before adding food and the course of cooking compared to an oven use is maybe halved or cut to even the greater extent. It appears a tad bulky, but it is neat when closed, replaces both an air fryer and a grill and it certainly makes a good appearance if the counter space is available. No fumes or smoke have been encountered whatsoever. The thermometer control appears to alarm and automatically shut off at the desired temperature which makes the cooking easier, though I would encourage people never to be distracted when anything is cooking in the kitchen.

Fast cooking, easy to use and clean.
Awesome ninja. So far I cooked, bacon, hamburgers, thick steaks and salmon fillet. All came out perfect with little effort. Used highest temperature on broil, lowered towards the end to 450. It marks well, sear great and everything was juicy. This unit is very easy to use, very intuitive, easy to control. Clean up? Just rinse or soak the dripped crusted pan and dishwasher does the rest. Wipe the rest as needed but there is no mess. Now, this thing does not smoke but still produces cooking smell so use it under the hood or you house will smell . Can't wait to make my sweet potato fries in it . Honestly. It does replace oven for daily cooking. Money well spent. Great price. Couldn't be happier.
