I really like the smart things app. It is pretty easy to use and sync with the oven. You can turn on and set the oven to any setting from the app. We havent tried any of the air sous vide settings yet only bake and convection bake. The precision knobs get super hot really really fast but I don't like how I bump them when I walk by or I have to look down to see them instead of at eye level. I haven't tried the self clean yet because I haven't gotten it dirty. I like it it heats to the right temperature, I have a oven temp gauge and it's accurate. There is no timer for the pre heat.
The burner dials go from Lo to 2,4,6,8 to Hi
