The stove top grates are what I would expect in a restaurant as they handle heavy skillets with ease. The multi sized burners are both convenient and more efficient when heating pans of relative size. The minute incremental adjustments on the control allow for a precise flame. The griddle/grill performs as you would want from a cast iron skillets. 
The oven being smaller heats up quickly and cooks more evenly than what I have been used to with a single oven unit.
I have had no experience within an air fryer previously so there is a learning curve, but no complaints. I like that the oven lights activate upon opening however there is no independent control so both ovens light simultaneously. 
Trying to activate the Bluetooth it did not sync initially, although I have not tried since I really don't have an interest in it as of now.
Overall quite pleased after a months use and love the way it looks.
