My husband and I decided we needed to start eating healthier so we purchased this. I tried an air fryer that was a different brand and ended up sending it back because it didn’t crispen the food at all. I also have a pressure cooker but it leaves food kind of “slimy” afterwards. The duet is great for combining the pressure cooker with the air fryer so that food can cook thoroughly yet crispy and have that restaurant level quality and taste.
