We bought this Duel Fuel unit to replace our 22 year old unitDF unit from another brand. I personally did the compleate instalation including changing from Natural gas to propane, All of the instructions were easy to read and follow. It took me less than a day athough I had to make some significan changes to the countertop both depth and width.

This is vastly better. 
The multiple range top burners are of different sizes, all are significantly lower than our prior unit. The result is that the heat ismuch more uinformly applied to the pot and pans above.

 The oven again has much more uniform heat distribution with in. The result is much more evenly baking.

The one item we would like to see is larger printing on the control panel and preferably back lit. The present can be quite difficlt to read in any thing but bright daylight.
