Product review (5 stars): Works great, fits great
Works great, fits great.  Took a minute to figure out how to slide it in and tip it up into place.  I thought I was going to have to cut it down the middle to fit.  If this happens to you, slide it in sideways fairly deep into the micro, then straighten and slant into place.  There are slots back there that hold it into place.  I have a GE Advantium 120 from 2006.
