I purchased this because our Instant Vortex 6 qt Basket Air Fryer wasn't big enough to cook the entire family dinner in. We use our Air Fryer for everything! I figured twice the size a 2 shelves would be a benefit and was hopeful it would fit a frozen pizza. Neither has been the case. Only the top shelf cooks through quickly if things are stacked I still have to send the 2nd shelf up and redo. It only fits a small frozen pizza. It's been a bit of a disappointment in that regard. It looks nice on the counter and cooks the highest shelf well. I just use my other Air Fryer at the same time in order to accomplish a whole meal at once. I guess I've discovered I'm more of a basket fryer girl!
