I like my air fryer, but there's certain things that a microwave just warms up better (pasta, basically anything that can dry out, etc). That said, my current apartment doesn't have a microwave so I am glad that I came in with an air fryer
Want to reheat a pizza slice? Microwave for half a minute/minute then in the air fryer to crisp it up. Ends up better than the first time around many times imo and done in seconds if you heat the air fryer up to 200°c first
I know lots of people love them, but I had one for a hot minute and found it totally pointless. I have an oven and a toaster oven, and for me it did not fit what I use the microwave for.
