Are Ninja foodies (or similar) worth it?

I suppose it all depends on what you normally cook. I use my Ninja a lot and only turn on the oven now if I am cooking more than fits in my Ninja. The other problem is baking - none of my dishes fit in the Ninja, although I could happily use it if I baked smaller cakes. I love that the Ninja is easy to clean, just wipe the fat out and then wash it out. You need to consider the actual machine you are buying and what it offers - some include grills, slow cookers, air fryers, pressure cookers and some are just air fryers, which may be all you want.

I often find that gadgets don't get used but I do use my Ninja a lot. I'm not sure of the costs but it is cheaper to run than the main oven. It is quite big so you do need space in your kitchen.

We use our Ninja a lot, I don’t think we’ve turned the oven on recently.
