I have the KNG481 running on propane. I have owned one other 48" range - and I can say this unit far surpasses my former Kitchen Aid appliance. I love that it this range has all knobs and no digital operation. This is my first experience with a gas operated oven. It is taking some getting used to - but with time and use I'm sure I will get it down! I am still trying to figure out how to know when the oven gets to temp. I am loving the variety of burner sizes. These are also more powerful than my previous unit which is such a luxury! I am able to easily adjust the temp with great response and accuracy. I also really like how the griddle fits very securely on the grates. It is very heavy - but also very efficient. It is also reversible which is handy. The racks are sturdy in the ovens. The blue interior is beautiful. I look forward to many years of enjoyment with this range.
