I have had this for a few weeks now and love how quickly the oven heats up and the burners.  It takes about 10 minutes to heat the oven to 450. People complain about the glass top, it seems like every other top on cleaning, use a sponge and cleaner made for that and wipe it off with a paper towel and you are good to go. The air fryer I am unsure about, I used it twice and put a pan under it with water and it still smokes a lot. The Wifi is nice, but the app needs to give more options on how much it alerts me. I get 3 notices when it has 3 minutes left or is done, it is kind of annoying.
