We have loved this oven.  We’ve been using it for about a month now, newly installed in our new home.  The survey feature is amazing!  Absolutely worth the extra cost to lose those small useless appliances and have one that can actually air fry a whole pan of fries, egg rolls, etc!  I even use this feature to crisp vegetables for just a minute!  Easy to use and can’t wait to get years of enjoyment.
