We were using the range and oven that came with the house when we purchased it. We never had anything with the same quality prrviously. We are in love. The power burner is powerful, the dual fuel is an absolute joy. The flame gets so low that it can melt butter but leave an egg uncooked. It's great. 
I wish there was a little more space for the mechanicals in back of the range, and my stainless cookwear leaves a silver marking on the cooking greats. Other than those minor annoyances, we would buy it again in a heartbeat.
