It is gorgeous and makes a statement in my kitchen.  As you can see from the attached photos that the zline brass burner covers have discolored after using a few times.  I did call and speak to the customer service department and they did replace them.  They really didn't have a reason for the change in color but she  said because I live it Florida and there is salt in the air or the humidity might have caused the color change.  (I do not live near the ocean and if you are boiling water, wouldn't you have humidity? )  The reasoning didn't make sense to me.  The 3 one is the new one.  #1 and #2 and discolored completely different from each other.  It  is somewhat "old school"  There is no cooking timer or notification to let you when the oven is up to temperature (it is fine but I'm use to having the notifications)  
Overall, I love it.  Customer service was ok.
