The unit looks very nice.  The griddle cooks great.  
The lid is difficult to open because it twists while lifting up.  
The air fryer is extremely disappointing.  One example: A couple days ago I was using both a stand alone air fryer and the Blackstone air fryer to make potato rounds for a large group of people.  The Blackstone air fryer took 50-75% longer to make the same amount.  This is after I let the Blackstone unit preheat for 20 minutes.
