Product review (4 stars): Perfect fit
This filter twisted right in to the spot for my Maytag Ice2.0 refrigerator.  Just make sure that after you put it in, you run the water for a while, cause there was a lot of junk in the water for the first gallon that came out.  After that the water tasted fine.  It may have stated in the instructions to run the water for a minute, but I didn't read those pesky instructions!  Saved money, the filter for my fridge at Lowes was $44.
