I have a Ninja air fryer and it is just OK so now I bought this grill in the 6 qt. size and it does exactly what the commercial says it does.  It is easy to clean and does a really great job cooking. I have done steak, pork and chicken and each has come out done right and after a rinse in the sink the parts clean up spotless in the washer. Much better than scraping the grill each time I use it and I know when I start a meal the grill is perfectly clean.
