Product review (3 stars): bulbs do not fit
This is the 2nd set of bulbs that I had to return.  The metal prongs are too far apart and do not insert into the female fitting on in the microwave.  The first set, I thought it was possibly an error - possibly an incorrect parts, etc.  With the 2nd set being incorrect as well, there is obviously a disconnect between the manufacturer of these bulbs and GE.
