I still haven't gotten to use all the features on this range but so far I LOVE IT!!!  I love that it tells me on my phone/watch when it's preheated/done, that I can watch it preheat & know approximately how long until it's ready.  The app tells me how much time is left to cook so I can run to the store, neighbors, etc & still watch the clock. There's so much to brag about on this particular appliance I could type all day!  The only downsides I have found to this point is I did not receive a manual so I know I am not using this to it's full capacity & the timer signal is so low I can't hear it.  That's why I love the phone app so much!
