Heavy duty, you can grill, roast, smoke, griddle a

[This review was collected as part of a promotion.] This is a heavy duty unit that does so much, its amazing! You can grill, roast, and has a spot for pellets that feed into it so its a smoker. You can use as a griddle or even a pizza oven however the griddle and pizza stone are sold separately but still how awesome is that. It will offer information on the screen that is very helpful such as close the lid when it time to heat up the inside, it shows the temperature as its heating and flashs what your temp you set it for. All options are clearly marked on the cooking unit so it easy to use. The instructions to put it together are very good, it also provides a link to a 3-D video which helped a lot. All the parts are lettered and they even include the tools needed. It will take two people to lift it up onto the frame other than that part it took about an hour all together to get it up and running. We are over the top happy with this and can't wait for spring and summer we will use to cook everything. I highly recommend this Ninga Flexflame outdoor cooking system.

I absolutely love this product. I was able to use it at a friend's house and tried to steal it! LOL! truthfully, I would never do that to her but I was very jealous and has been trying to get one of my very own so now that Sam's Club has them I believe this will be my next big purchase. might have just about everything ninja has put out and when the food came out I'm on my fifth one because I used them so much that I blew up the first two. I've never been disappointed by any ninja product and if you're interested in a grill then I suspect this is the place you want to be! it also comes with two griddle inserts which makes life even better. please do your research because I did mine and I decided that this is definitely my next purchase. until then I'm always over at my girlfriend's house bugging her to death and using hers. I hope this helps you make the correct decision for you.

Backyard upgrade I didn't know I needed

I went in expecting a good grill and got a whole outdoor kitchen. One system covers grilling, smoking, roasting, griddling, and pizza, and the results are great across the board. The best part is how easy it is. It lights every time, preheats to 600°F in about 7 minutes, and the convection airflow cooks food evenly, so there are no hot spots or burnt edges. Cleanup is simple too, since the design keeps debris from clogging the burners. It's sturdy and weather-resistant, and it looks sharp in stainless steel. Between the roomy cooking surface and the flexibility, it's been the star of every get-together since I set it up. If you're on the fence, go for it. One purchase replaces several, and the food is better for it.

Thoughtful, Consistent, and Easy to Use

[This review was collected as part of a promotion.] Packaging was well thought out. It actually made it easy to start assembling. Most other packaging is just to be efficient, but this seemed efficient and intentional. All hardware was labeled extremely explicitly, I was able to assemble all in one try! Assembly tolerances were also tight but with enough movement not to make any bolt too frustrating. I definitely needed a second person to install the actual grill on the base, but otherwise I could do all myself. The grill itself is large and can handle two or three racks of baby back ribs. My first smoke session was 2 racks and a 6 pack of chicken thighs. All came out with great flavor, utilizing the pellets given as samples in the box. When grilling chicken, the fan helps keep everything brown and crispy, and frankly I have never been able to achieve such great color on grilled chicken as I have with this grill. As for the cons - my biggest heartache is with the fan. The grill needs to be plugged in to use and the fan is constantly running. When I am just looking to grill up some burgers, it seems a little excessive. I can light the grill, then unplug the cord, but the manual says dont do that. Probably they dont want me to burn up the electronics, thus the fan needs to be constantly running. Second Con - The smoke flavor was REALLY clean. Thus is the case will all non-wood burning smokers. I have come to expect a little sootiness from my smoked meats, and that underlying bitter flavor isnt present. For those who would rather not ingest the carcinogens, this is probably a Pro! Overall, I would recommend this for a friend who is looking for a combo and ease of use. I have two very young children and sitting next to a smoker all Saturday with a beer is no longer in my future. This gives me high flexability to go and live my life while the brisket smokes. I can also dial in the temp for grilling and roasting. I plan to use this for Thanksgiving turkey with a dual smoke/roast. Should be good. That all said, I am just a man with a grill.

Finally, one outdoor cooker that does it all

It heats up fast, reaching 600°F in about 7 minutes. The CyclonicHeat-iQ system keeps the temperature even, and the raised gas ports keep the flames lighting reliably, with no clogging from drips. The 544 sq. in. cooking surface is plenty for a family cookout. The build feels solid and weather-ready, and the stainless finish looks great on the patio. Pizza night is now my favorite thing to do with it (the pizza accessories are sold separately, but worth it). If you want one product that handles weeknight burgers and weekend smoked brisket, this is it. Highly recommend!

A versatile outdoor cooking system that makes cooking more convenient.

I really like the Ninja FlexFlame Outdoor Cooking System. The design is sleek and practical, and it's nice having a cooking system that can handle different outdoor cooking needs. It feels sturdy and well made, and the setup is pretty straightforward once you get everything in place. I also appreciate that it's designed to make outdoor cooking more convenient without needing a bunch of separate equipment. Cleaning may take a little extra time after cooking, but overall, it's a great option for outdoor meals and gatherings.

Best grill on the market

I am obsessed with this grill. Best grill on the market. Leaves full blown wood pellet and charcoal grills in the water. I'll never own another grill.

Conventional

I never received through influenster but I was really good at convincing my family that we needed to get one. It was a fairly easy process to assemble so don't be intimidated. One of the features I love is the temperature control you get the benefit of cooking like you would if it wan an oven BUT it's grilled. Yes read that again!! This was pure genius.

Great grill but…

When I bought this grill, it was wonderful was met everything all the expectations that I had except that it was covered in stickers that when I took them off, it left behind significant sticker residue that I have not been able to get off in a year. it's extraordinarily frustrating because my beautiful grill is covered in nasty sticky, residue covered in dirt and other things that now stick to the sticker residue. It's very disappointing that these were not just basic clings that could easily be removed instead my grill looks like garbage.

Hi there, Thank you for taking the time to leave a review. We're sorry to hear about your experience and understand how frustrating it must be to have sticker residue remain on your grill long after purchase. To help remove stubborn adhesive residue, you may wish to try products such as Goo Gone, isopropyl alcohol, or Dawn Powerwash. Applying the product and allowing it to soak for a few minutes before gently wiping the area may help loosen the residue. We appreciate your feedback regarding the stickers and will ensure it is shared with the relevant teams for review, as we understand how disappointing it is when a product's appearance is affected in this way. If you need any further assistance, please contact our Customer Support team here: https://support.sharkninja.com/contact-us Kind regards, Ninja Kitchen
