Product review (4 stars): Very nice range with a couple small flaws
This range is wonderful. It is very sharp looking with a nice quality appliance feel to it. I have had mine for about 13 months and I do a lot of cooking on it. The oven works very well and cooks accurately. It is quite large inside compared to most of the 30" ranges due to the narrow compartment walls. The lower warming oven is very useful and we use it constantly.
The cooktop burners have excellent range of heat and the flame adjusts very accurately on each of them.
The cooktop however is where the flaws come in. The burner caps are coated with a heat resistant coating which is charcoal gray in color. It matches the color of the grating. Foods/oil/fat will stain these surfaces. You can clean off the bulk, but it will leave behind a stain. If you use anything heavier than a plastic scrub pad, it will scratch and remove the coating. I have had two spill overs of boiling water that landed on first the left rear burner and later it happened on left front burner. Both of the burner caps lost large chunks of the coating when the water contacted them. The burners would still function just fine, but they look terrible. Burner caps on a range of this quality and cost should be able to withstand some hot water.
Also when you are cleaning the Stainless steel surfaces, don't use anything but soft cloth are a sponge. Good stainless steel is soft by nature and will easily scratch.
With the exception of the middle elongated burner, all of the burners produce a lot of very controllable heat. When you use the included griddle on the middle burner, it takes several minutes before it heats up properly.
The digital controls are very intuitive and easy to see and use. All of the range top components remove easily for cleaning.
I have found a product called "Sprayway Stainless Steel Cleaner and Polisher" that works excellent for this range. (got it a Sam's Club)

My sister in-law bought one of these ranges and she has had the same problem with the burner caps chipping off.
When it first happened to mine, it was still under warranty and GE promptly shipped a replacement. The second incident happened just a month after my warranty expired. I contacted GE and they are shipping me another one and they said they would have their product specialist contact me. Hopefully for a product this expensive, they will come up with a satisfactory re-designed fix.

Overall I am very satisfied with the looks and performance of the range, but something needs to be done about the burner cap coating issue.
If it were not for the burner cap problem, I would have heartily given this range a 5 star rating.
Be sure to find some of the Spraway Stainless cleaner, it works great.
