I love this range so much! It's really nice..especially compared to the one I had before! It was super easy and fast to put it in the place of my previous one..it fit perfect! And it connects to wifi and an app and that was easy to connect also. It has a built-in air fryer..I haven't tried that out yet but I'm sure it works amazing. You really don't have to wait for it to pre-heat..it's really fast. As far as the app that connects with the range..it let's you turn the oven on and let's you set the temperature and you can set a timer also. This is just an all around great range! I couldn't be happier with it.
