Product review (4 stars): Well Made Replacement Part
My GE Range is about 6 years old and this is not the original replacement part.  It is actually made better than the original (all metal vs. plastic original).  The only reason it doesn't get 5 stars is it's not the exact same size as the original.  It's probably about 5mm less in diameter than the original...you don't notice unless you really look hard.
