We've had it about a month and I'm enjoying it as I'm learning to cook on it.  I'm getting used to the temp setting for stove top and I do like 'fast boiling' with 3 choices of widths on the left front burner.   When using the oven... it heats up so fast!!  I'm used to 20+ minutes but this seems to get to full temp in less than 5 minutes.   
As for the air fryer, I'm not sure if I'm doing something wrong, but it doesn't seem to be any faster than a hot oven temp.  I have a small air fryer and it cooks faster and hotter.
I dig the blue interior and the big handles for the burners. It gives it that faux look of a gas oven.  
We are installing a wood slab shelf above to set seasonings and kitchen "stuff".  Very hip and sleek.  Matches our refrigerator and dishwasher.... We are an LG family!
