I have been using the Kucht 36" dual fuel range for about 5 month now without issue.  I love the power of the burners and while I wish the lowest powered burner was in a different location, that is purely a matter of personal preference.  My biggest issues to date date both have to do with the oven cavity.  I wish the racks were on a glider system as they are large and tend to stick which can makes it somewhat hard to maneuver when you need to pull out a hot loaded rack and the upper rack had a lip on the back which has a gap that is just high enough to get items stuck in (especially soft dough items like pizza). 
Overall, I have been very pleased.
