Product review (1 stars): Poor quality and service.  Several standard deviations from the norm.
Bought this as a replacement for an old 20 year old cooktop that developed ignition issues. Arrived with bent knob. Packing was flimsy and the top left burner knob was bent. It appears that it was taped for transport a bit too aggressively. Unable to turn that burner (top left) on. Called service via GE warranty who came out to eval and part back ordered for a few weeks. Also discovered that top right burner knob is sticky and hard to turn on. The top right burner also does not seem to be sensitive to the position of the knob and produces a weak flame. It takes that burner about twenty minutes to get water to a boil. Shared this with technician who seemed unconvinced of failure as a flame appeared. So in summary only 3/5 burners useable, and unclear that upper right will ever be fixed.

Update:  I had a service call, called the day before to confirm the time, and the morning of. Was called during the service window and told technician would not arrive.  No explanation, no apology.  Got bounced around phone tree to no avail to try and remedy the situation. Had appointment automatically scheduled when I would not be there.  Called and asked for replacement as the other control knob is failing. After 2 hrs on the phone was granted this.  Asked to be escalated multiple times and was declined.  GE scheduled delivery and installation with a service that does not install cooktops in my state.  Wrote a complaint letter to consumer relations.  No apology, no remedy, no acknowledgement of any wrongdoing, just a sentence telling me to identify a service provider that can install the cooktop in my area.

I am a fairly active consumer.  I purchase a dozen products from amazon a month.  This is experience is the first one that has prompted me to write a negative review.  I will amend my recommendation to avoid this cooktop to avoid GE entirely.  The customer service is reminiscent of the 1990s DMVs.  I will continue to update.
