I have this one and it’s really good
ninja is mid ngl, round basket sucks and online shipping is a hassle. just go for the philips, it's way easier since there's a store warranty nearby
Honestly all the air friers are the same I have the na231 and honestly there is no difference, only difference between these two is you can see the food without opening the basket. If you are on budget you can go for na130 if you want to spend and have convinienof not opening the basket to check food go with the na231. Only if you are digging for concerns i would say na130 nob may give problem with the nob after you use it many times as it is a moving part. But again its way ahead in future and easily fixable.
I have the NA231. I like it a lot. It works very well. It is easy to clean. PTFE is fine. Air fryers don't get hot enough for it to be an issue. Personally I would not choose the Instant Pot because it doesn't have a window. I use the window a lot and would never buy an air fryer without one. Of course that is just a personal preference.
First of all, stay far away from 2QT. That is way too small. Also, there are some decent cheap brands like Gourmia and Chefman. I actually got a nice Philips 6.6QT pretty cheap ($90 CAD/$65 USD) and I love it. Got my mother an 8QT Chefman for the same price.
5ish minimum. I use mine for just me and I wouldn't want much smaller than my 6.6. A light eater might be ok with like 4QT but I guarantee you will soon wish you had something bigger. Better too big than too small.
I have the NA231 and honestly we use it at least 4 times a week. We got it as a wedding gift so I haven't researched about any other brands but this definitely does it's job really well. It is pretty easy to use, easy to clean, cooks well, the size helps when it comes to french fries/ wedges I can put a lot more for 1 batch.
