bought this to replace an old and failing electric range. really like the 5 burner cooktop, especially the middle burner where i can use my cast iron griddle. i prefer the cast iron to the included aluminum griddle. the oven heats up quickly and convection feature does seem to help with cooking speed and evenness.  the air fryer works much better than was expecting.  the geek in me does enjoy the smartthings connection but it is mostly a novelty.  you don't have too much control over the range (by design since it's gas) but it is cool to see the status of the oven, burners and any timers you set.   one thing i do miss from my old range was a larger storage drawer. overall very happy with this purchase.  i received compensation for this review but the review is my own.
