No, I doubt it.
I got one in the spring, and I am using it, but as I already had an IP (pressure cooker with knobs on) and a separate slow cooker the only benefit is the air fryer function, and I find that the (cheaper) Tower one I have at our lodge is better for that. The tower one has shelves, and is more like a mini oven, whereas the Ninja is a pot that you cook in. You have to add racks to cook two things at once, and they are a faff. The pot is round, whereas the shelves on the Tower are square/rectangular, so much easier to fit cooking pots into. Getting things out of the Ninja is fraught with danger, whereas the Tower is much easier. You can fit a pyrex casserole dish in the Tower, but you have to cook casseroles/lasagnes etc direct in the Ninja, which I don't like as I prefer to serve food on the table rather than plate it up, and the pot is not suitable for that.
If I didn't have an electric pressure cooker I would feel differently, but if I'd had the Tower before getting the Ninja I wouldn't have got it, I would have gone straight for another Tower. Both are cheaper than using the oven though.
