Love this Combo Microwave!! 
The microwave; works  as it should.
 Air frying; worked great for chicken nuggets ( placed in crispy pan, then placed on tall rack)
Conv oven ; worked very well, as we made a frozen lasagna  & garlic bread (placed on top of  little rack, but not sure if that is what you were supposed to do)
Have not tried the other features yet, as there are alot, but will review them once I do!! 
 I only wish it would come with more instructions on how to use all the functions, crispy pan & tall-short racks, as I'm still not sure which one to use with what functions. Had to read other reviews for clarity.
