I bought one for myself this summer and gave this updated model to my parents for Christmas. They are thrilled! My mom is relearning to walk after an illness and my stepfather has been most of the cooking and taking care of her. My reason, personally, that I say it changed my life is that I rarely use the oven anymore. My husband and I use this to air fry chicken breasts. Without looking at the directions too closely, I evoo'd, s&p'd, herbed the chicken breasts, hit start and in 15 minutes (no preheat), flat, we had the most amazing, juiciest, flavorful chicken breast we have ever had. I am a great cook, but in order for my chicken to be that juicy and tasty, I would use a vat of chicken broth or the like and have to baste them in the oven. Between the time, the cookware cleanup, and the good - but not THIS good! - chicken, this air fryer has changed my life! Besides that, I don't need to make or buy chicken stock or bone broth to baste my chicken anymore or let my chicken cook in its own fat.
We have also used it to heat up pizza, Jamaican patties, tortillas, pita, frozen Brussel sprouts, reheat any veggie actually, potato fries, a chimichanga once - just a lot of things I would usually end up throwing away.
The cleanup is way too easy without the parchment insert if you decide to not purchase them. I didn't know that was a thing, so it took a few months to start using a parchment liner, but it still cleaned super easily. Better with parchment, and you can also use regular non-formed parchment paper, to save money.
My stepdad is really thrilled with it. It saves him from back ache from opening or shutting the oven door, he will be able to clean it easily, cook healthier to help with his blood pressure and cut down on a lot of work that would otherwise take time away he would rather spend with Mom. I highly recommend this NuWave air fryer. It is SO EASY!! It's brilliant. Worth every penny.
