We've had this range now for nearly 3 years. 
I'll start with the negatives. The oven heat spills out more than any oven I've ever owned. The marble tile backsplash is burned and has discolored yellow because of this extreme heat coming out of the oven. 
Secondly the oven takes around 7-10 attempts to light. Squatting down watching the flame go out over and over and then after a minute or so of attempts it finally stays lit. This issue has been persistent since we bought this oven. We use it daily and don't think this is how a $2000 range should function.
The positives are quite obvious. It is a good looking range with a lot of space to cook. We have used the center burner with a wok which is a nice feature. 
Personally I wouldn't buy this range again because of the noted issues.
