We have been using our gas oven for about a month.  So far, it has been nothing short of great!  The stove top burners all function as designed.  The only problem is finding a burner that will simmer.  We are using a back burner for that purpose and it works well, just a bit hard to reach.  The oven is fantastic.  My wife bakes bread (really good bread) and is anxious to try the steam bake.  This is a really good machine.
The only improvements I would recommend are these:  Make the dial control words with more contrast so that they are easier to read, especially on the oven control.  Secondly, some "How to..." videos including some "When to..." advice concern the different oven settings.  For example, when is it better to use the steam roasting vs. slow roasting?
