I bought a Cosori air fryer a few years ago after reading about them. I thought it might be a bit of a gimmick at first, but it was one of the best thing I ever done. Two years ago, I upgraded to a Ninja Foodie, that really was the best thing I have done, I rarely use my full size oven now. I cook everything from full chickens to curries, casseroles to bread, soups, roast potatoes, chips and wedges, rice puddings and cakes and pies, it makes the best toasties ever.... It bakes, roasts, steams, pressure cooks, slow cooks, air fries and even dehydrates, it is a very versatile machine, it certainly is a lot healthier. It cooks most foods faster, thus it's more economical and its very easy to clean. I've saved a fortune on my power bills since I started using it. Most of my family have changed to either the Ninja or an air fryer of some sort and they swear by them. Initial outlay can be quite high dependant on model, but as I use mine everyday, mine has paid for itself in spades. I would highly recommend one, do a bit of research, but I feel the Ninja Foodie, although expensive, is by far the best machine. You won't regret investing in one, which ever one you choose.
