  • Love my Ninja grill
Style: 6-in-1 With Thermometer
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.

  • A big step up from even the previous model
Style: 7-in-1 With Thermometer
I have owned the previous top-of-line grill model - the FG551 - for over a year, and that device transformed how I cook more than any other piece of kitchen equipment I've ever come across. It's just so easy to get perfectly consistent results when cooking meats, and when you're done, you can just toss the grate, pan, and screen straight into the dishwasher. It's not a charcoal/hardwood grill but you can get plenty of flavor with rubs and marinades. I stumbled upon this new model on Amazon while looking for a replacement lower pan for my FG551, as I'd used and washed the one that came with it almost every day for a year and it was starting to crack at the corners (still usable though). The big difference is that this new one does not rely solely on heat generated by the air fryer element at the top - the grill grate itself has an integral heating element, and when you install it onto the base, it makes electrical connections with two contacts that supply the current during cooking. I bought one immediately, and it has not disappointed! Compared to the previous model, unsurprisingly, this one cooks faster, which solves a major problem when cooking thicker cuts of meat. Previously, if I were cooking really thick steaks, I wanted to use higher temps to get better browning but couldn't do so because heating by air alone is just too slow. The grill grate is a fairly massive piece of cast iron, and the preheat does get it up to temperature so you can get grill marks/sear, but it can't retain that heat very long because again, air isn't an efficient medium to transfer heat from the air fryer heating element into the grate to keep it hot. So if I ran it on high (500F) like the manual recommends, I would get a crunchy, charred shell around a rare steak; the solution was to reduce temps as far as low (400F), depending on the steak, but the results were never as good as with thinner cuts. This new unit does not suffer that problem because the grate itself is heated from below, and I can now cook everything at higher temps across the board because they cook so much faster, even for really thick cuts or when using marinades that would have burned on the old model. Clean up is similar to the previous model, but you have one less piece to throw in the dishwasher - the heated grill grate replaces a roasting pan and a separate grate that sits inside it. The only issue I have with this new design is that the aluminum grate is not coated in any way on the bottom, leaving an exposed aluminum surface; anyone who has ever put a raw aluminum pan in the dishwasher knows that it will come out with a grey/black oxide layer on the surface, which is not toxic or harmful in any way, but is annoying because it gets on everything it touches. I just hold the grate by the edges, avoiding the bottom surface, and only ever handle it to transfer between the grill and the dishwasher that resides directly below it. Once installed in the base, that surface is not exposed in any way so nothing will come in contact with it. Honestly, small price to pay for how well this device works. Very happy with this new model, and I have retired the old one, which served me well. These are the class of the field when it comes to an indoor grill, and they are great air fryers too. I don't really use griddles so I can't comment on that part, but it is a pretty slick feature on top of everything else this thing can do. ... show more

  • Quality unit.
Style: 7-in-1 With Thermometer
This is one fantastic unit. It takes a little getting used to at first but once you get the hang of it you will love it. I like the griddle the best. Easy to use and easy to clean. Cook bacon, scrambled eggs, or sausage with ease. You can use the grill to cook a steak from frozen if you want or right out of the refrigerator with the lid open or closed from inside your kitchen. The air fryer works great too. It comes with a booklet full of cooking charts and recipes to help you get started. ... show more
