Product review (3 stars): While we are satisfied with the cooktop itself
We purchase this model cooktop from another vendor approximately 7 months ago.  While we are satisfied with the cooktop itself, I wish we had done more research before purchase.  We went with this model partially because of the metal cooktop knobs, but what we didn't realize is that the *shaft* of the knobs are cheap plastic.  Now, seven months in, all five have broken and do not hold the little metal insert properly.  This means that the knobs for my high end cooktop are partially held together with scotch tape while I wait for replacements.  Extremely disappointed in this and expected better from GE for their more expensive products.
