You’re relative sounds like a tool. It’s a nice product, but it’s very weird and rude to me, for someone to just buy an appliance for your home. It’s expensive enough that you feel obligated to keep it, but many people don’t have room for that type of thing. It’s just weird, like someone coming into your house and just hanging a large picture on your wall. As for the appliance itself, it can be useful. It’s not a fryer. It’s a high powered convection oven. It does a very good job of oven things, but faster. It’s a decent replacement for a toaster oven, if it’s shaped that way. We have a ninja foodi with a pressure cooker attachment. It’s good, but we probably under utilize it. It’s also a little small. So it’s sometimes awkward to get everything in. You aren’t cooking for a crowd with then either. It’s good for a couple of people, though. It does a great job in reheating things that don’t typically reheat well. Pizza, fried foods, etc.
My foodi tendercrisp is 8 years old and I use it several times a week as more than just an air fryer. Convection ovens with air fry modes are very lackluster.
Decent for the price with okay warranties. I have a Ninja Foodi air fryer/pressure cooker/slow cooker/all in one jawn that sits on my counter and get's used like 3 times a week minimum. It's one of my favorite appliances in my kitchen because I primarily use it as an air fryer but it can also be a second slow cooker for when I'm making a huge meal. The steamer function on it is pretty tight as well, boa buns come out perfect from it. The coffee makers are also decent but I wouldn't use them for high end things like espresso. A simple ninja drip coffee machine will be just fine though. Blenders again are decent but ill not outperform something like a Vitamix or more high end. Knives? The knife block is okay but I hate pull through sharpening systems and am generally against buying sets as a whole. You only need a few good knives. Generally Ninja makes decent things that will do the thing they are advertised to do. They won't do them exceptionally well as compared to products that specialize in said task but they aren't poor quality items either.
I love mine and use it daily. I even bought a ninja combi because I wanted more options lol. I like the ninja foodi because it's also a pressure cooker, and makes perfect rice and hard boiled eggs. I use it for bagels/waffles/toast daily, and usually reheat things in it. If you make frozen foods like fries and chicken nugs, it's good for that, and if you like roasted veggies, it's perfect for that too. My oven has an air fry function, but it doesn't work as well as a standalone one.
I also do not like one job kitchen appliances. I have the ninja foodi, which is a pressure cooker, slow cooker and air fryer all in one. I use it almost daily!!! Steaks, veggies, rice, pot roast, recipe book says I can even make yogurt and cakes/breads in there that I haven’t done that. I basically only use the oven for large items now
We have a ninja foodi since it serves several functions. Air fryer. Slow cooker. Pressure cooker. Dehydrator. Steamer. Etc. We live in an RV full time and have extremely limited counter space but it still made the cut for us. I'm currently making shredded beef for enchiladas in it. It's easy enough to store under our dinette seat.
