Product review (2 stars): Wish I didn't buy it!
I have owned this oven for about 2 years now and I really wish I purchased another. It does have it good points, but I find myself more frustrated with it as time goes on.
They put two large burners in the front and two small in the back. Well, when I have two large pots going on the front it's almost impossible to reach over them and use the two smaller burners in the back. Mine is connected to propane so I don't know if that makes a difference, but the flame adjustment is just terrible...they all seem to want to burn on high...even when I turn the knobs to the lowest settings it's still to high, and yet the center burner never seems to go to that high setting? The front right is a simmer burner, but when I lower it to simmer I get a black buildup of soot and it start to give off a propane smell so I can never seem to use it for simmering anything. The front left burner does do a great job of boiling water very fast though. If the oven is on the vent fan will start blowing on the two burner on the right side and has blown them out on occasion, only the smell of gas alerted me to this. The blowing flame makes simmering anything impossible....even if I could simmer!
I recently noticed my knobs are all wrinkled and crumbly underneath..never noticed it before, but the knobs do get hot when the oven is on. I have read other reviews about people having them melt, so my problem is probably also from the heat. I have just contacted GE about this so I'll let you know if their customer service will stand behind their product or not. The knobs are really cheap for the high price of this stove.
I used to convection oven maybe 8 times and have since given up. It takes TWICE as long for anything to cook when I try and use it. I really wish they made an oven without the convection...I really didn't want it in the first place and had to pay hundreds extra for it because this was not an option.
I do love the look of this oven, the stove top grates are nice and thick and I wanted the five burners, but I do not feel this oven lives up to the cost or high quality standards.

Update: Customer service did respond quickly to my complaint about the melting knobs. They sent me out replacements and instead of plastic they are now using stainless steel as the standard, so I assume this was a frequent problem. The skirt that goes behind the knobs is still plastic though.
