Product review (3 stars): It worked. Not sure if genuine part though.
I'm not sure but what I got came in a GE box like shown in the pic but there wasn't an instruction manual like one shown but came with what looks like a xerox copy of how to install it.  The part itself was gray and not white, and was slightly longer than the original, made with what looks like cheaper plastic.  The top clips also do not clip on as expected.  You'll have to hold it in when you put the drum back and fit the drum into place.  But over-all, it worked
