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.

Great grill with a bunch of accessories

[This review was collected as part of a promotion.] First grill and I can say I love it from how easy the assembly was and the nice design and build quality it has setup was easy just the grill and building the base it's so easy to cook and use from the easyness of changing grilling modes and even turning on the woodsmoke with the flavor woodsmoke button on the grill even more things I like is the accessories u can also get like the flat griddle I plan on buying and more grease pans and a half griddle and u could even decide on a pizza pan cooker something I was I could do with this grill is fold the side trays down but it's still a awesome grill.

We are loving it!!!

[This review was collected as part of a promotion.] Great for cold temperatures. Heated up so fast. The ninja doesn't have a smart app so we are having to use a smart thermometer to help with that. You would hope it would be included for such an expensive piece. Our traeger had it however that sucker took forever to get to temp so each have their pros and cons. We are so happy with this and cannot thank Influenster enough. It's gonna be well used. Also, this thing is a beast haha was not expecting it to be this big.

Great all around option

[This review was collected as part of a promotion.] This cooks nice and even due to the convection. It cooks fast when you want it to but great for using low and slow for barbecue. The wood cup needs to be bigger so it doesn't need refilled every 30 minutes. Good size and easy to use.

Yes. Yes. Yes!!

[This review was collected as part of a promotion.] First of all it's a beautiful grill! The assembly was easy enough and I appreciated the audio and visual instructions. So far I've only done chicken wings but i can't wait to use it for more. It heats up quickly and cuts down on cooking time but still cooks evenly. Next time I'll try out the smoker to add a bit more flavor.

Absolutely amazing grill!

[This review was collected as part of a promotion.] This is a very versatile grill that will grill, bake, smoke, and griddle. The set-up instructions were very organized. It did take about an hour to assemble, and having some mechanical skills is helpful for assembly. The only real issue in putting it together was that the screws that hold the control board in place by the right tray have one bolt that is difficult to install, as it's obstructed. Overall, it is a very sturdy grill with a nice storage area and locking wheels, making it easy to pull out to use and put away when done. It's very easy to use, and my teen son has really taken to cooking his own meals on it. Pizza has been his favorite, and I purchased a pizza stone to facilitate that. The pizzas turn out delicious. The smoker pellets are nice. It takes about 5-10 minutes to get them going. They do work best for cooking longer than 45 minutes and add a nice amount of flavor when doing so. When the lid is closed, the fan creates a convection oven state. This allows it to heat up quickly, allows for a consistent temperature, and leads to really even cooking. If you leave the lid open, the fan shuts off, and you can use it like a regular grill rather than a convection oven. It didn't come with a griddle, so we haven't been able to try it yet. It has 4 cooking cycles on the settings, which allow you to do anything from slow cooking a roast or allow for a quick cooking situation for hot dogs and hamburgers. It uses both propane and has to be plugged in. The built-in igniter is quite handy. Also, the secondary rack is easy to remove for a larger cooking area. It has 3 burners that can be used in any combination, allowing the cooking of different items at the same time, like meat and vegetables. Other nice qualities include: 1. The spacing of the grill slats is close, allowing for less food to fall through. 2. It has a very large oil trap, which is nice compared to all other grills I've used. 3. This is one of the best grills for even cooking grills that isn't an infrared grill. Ultimately, I am very pleased with this grill. It's honestly the best one I have ever owned.

Hungry

[This review was collected as part of a promotion.] This grill does it all ! After a quick assembly- We were most excited to use it as a pizza oven. We had to order the peel and stone prior to testing it out. I am SO glad we did ! The pizza cooked in a couple minutes and it was crisp and delicious with the perfect cheese pull. Everything you want in a pizza. I am surprised by the size of the grill. It's not so big that takes over the whole yard- which is something I was concerned about because it does so much. We have also used it to smoke a steak then made some delightful steak sandwiches on the griddle. I am looking forward to testing out all that it can do. Roasting chicken is next on the agenda. Great machine that is easy to clean. You will not regret this purchase !

Backyard luxury for grill masters everywhere!

[This review was collected as part of a promotion.] This. Is. The. Mack. Daddy. Of grills! If someone in your life is looking to upgrade from a grill to a grill, a small smoker, a rotisserie, a pizza cooker, you name it…this is the system you are looking for! My husband is obsessed. We just ate the best. Steaks. Of our lives! You could taste the hint of smoke he blew in to assist in their grilling. Chefs. Kiss! He did say smoking ribs in there would take effort and a lot of refilling of the pellets but it's doable! In regards to set up and assembly, the directions were crystal clear and the bolt holes, everything lined up like a dream (not something my husband is used to in assembling things, especially grill parts!). The grill weighs a lot but is on wheels making it easy to pull in/out of a garage. The quality is just- you can feel it! Of note- outside of propane the grill needs a power source for use of the automatic temperature control, etc, so you might want to pick up an extension cord to go with the grill if you're bringing it home or gifting it to a loved one. Also, the side tables do not fold down so just be aware of that when planning on storage locations, but whew whee! This grill is truly a backyard dad, grandpa, new homeowners, dream! Looking forward to many summer grill outs on that distant horizon!

All in One

[This review was collected as part of a promotion.] I'm used to no-frills propane grills, so I didn't expect to be this wowed by the Ninja FlexFlame. Yes, it's more advanced than a traditional gas grill, but that extra tech really pays off once it's up and running. The digital temperature display is bright, clear, and incredibly satisfying to use. Being able to dial in an exact temperature instead of guessing feels like a major upgrade. What truly sets this grill apart is how fast and evenly it heats. Thanks to its powerful built-in fan, it reaches high temperatures in minutes and delivers consistent heat across the entire cooking surface. The results were impressive: sausages blistered beautifully, burgers developed bold sear marks while staying juicy inside, and corn came off charred and flavorful. This thing means business when it comes to grilling. The fan-driven convection system makes a noticeable difference. Heat circulates efficiently with the lid closed, which not only speeds things up but also helps food cook evenly. It gives you that confident “this is going to turn out great” feeling every time you grill. The FlexFlame's versatility is another huge win. The half-griddle produces gorgeously caramelized smash burgers, and the pizza stone delivers crisp, well-baked pizzas with puffy edges in surprisingly little time. Everything feels intentional and well-engineered, making it easy to jump between cooking styles without a learning curve. Even the smoker function adds an extra layer of flavor, imparting a rich, smoky taste that elevates foods beyond standard grilling. It's a fun bonus that expands what you can do in your backyard without needing a separate appliance. At its core, though, the Ninja FlexFlame shines brightest as a grill, and it's an excellent one. It heats fast, sears beautifully, and delivers consistent results every time. For anyone ready to step up from a basic propane grill and wants power, performance, and versatility in one sleek setup, this grill feels like an exciting upgrade that makes cooking outdoors genuinely fun.

Wonderful Grill!!!

[This review was collected as part of a promotion.] We have been blessed with this Ninja grill! It's very sleek and attractive on our patio! It's also very good quality. It's light enough for me to move around if needed. It's got the wood chip smoker and came with 2 bags of wood chips! It does plug in to display the inside temperature which is something our older grill does not have. You have the propane compartment underneath and room for other products! You can smoke a pizza, and it has the slow cooking options. We cooked 3 meats: salmon, lamb, and steak together and they all turned out perfectly. Using the propane, our dinner only needed about an hour for everything which is much faster than our older grill. My husband loves it!! Overall he gives the grill and performance a 12 out of 10. He loves it that much 😊 Setting up was challenging though and he gave that process a 6 out of 10. It took him about 5 hours to do and he's experienced with building off of instructions and this was due to the drawings not always being clear. The instructions were great in that each step had its own separate package of tools so you don't need to worry about missing a part. After set up, he easily put the propane tank on and rolled the grill into place. He set the temperature he wanted it at which is a luxury we aren't used to. The power lowers when you open the grill, probably to save energy, then it picks up when closing the lid. One thing I'm not a fan of is the noise it creates, a humming noise. But it's due to the fact it's electric. We can easily overlook this though for the convenience and time saving this grill provides. I wanted to post more images and videos, but the ones we posted clearly show the beauty and ease of use. We absolutely love this grill and would recommend to anyone.
