Product review (5 stars): You can taste the difference!
I have had this range for over 6 years and love it.  It was in the apartment brand new when we moved in so I did not purchase it through amazon.  It cooks and broils meat and fish better than anything I have ever used before. You can literally taste the difference.  I cook almost every day and have had no issues with the oven.  The only thing that happens for time to time is the top of the range clicks when you turn on one of the burners (starter click).. So I just reignite the range a few times and it goes away.  I don't think I could live without this oven it's that good.  My recommendation would be to buy it brand new from an authorized Viking dealer and you will likely not have any issues.
