Product review (5 stars): Perfect: just remember do NOT touch halogen bulbs directly with your skin/fingers!
Fit my GE Spacemaker 2.0 OTR microwave just fine!  Warning though: nothing in the packaging reminds you or alerts you to NOT TOUCH the BULB directly when you install it.  Remember that for any halogen bulbs!!!  Wish they had put that "reminder" in with the product when they ship it as there are probably consumers who don't know, or may forget, that aspect of halogen bulbs (i.e. don't touch and therefore do not get any oils etc from your fingers, onto halogen bulbs).
