So far ok. We converted from gas to propane stove top & oven. Haven’t used the air fryer yet, still getting used to the various stove top sizes. Very disappointed in the griddle burner, even on high it doesn’t get hot enough for cooking pancakes or takes forever. The other very disappointing thing is there is no manual way to light the oven, so if your electricity is out you can’t use the oven.  I don’t need fancy WiFi I need to be able to use the stove with my propane not electricity. 
For a basic gas/propane stove top fine but may as well have an electric oven since you need electricity to turn it on.
