Product review (4 stars): They provided me great visual preparation on what to expect
This resolved the water and ice problem I was having with my Maytag refrigerator (as the part number is designed for both Maytag and Whirlpool.  I had to call Maytag to ensure it was the same part number.  Even though I knew that Whirlpool manufactures Maytag products as well).  A few comments:  (1) Watch a couple of youtube video's on this subject.  They provided me great visual preparation on what to expect.  (2) Make sure you have the proper tool (which one of the videos advised me to have.  I went out and purchased the one I needed.)  (3)  You will have to move your refrigerator out from the wall a few feet because of the working room you will need.  (4) For ease of ensuring any existing ice melts I recommend unplugging your refrigerator for 24 hours.  (5) I had to remove two screws from the front grill to enable me to get to where the wheels were. So I could move my refrigerator forward.  These screws were slightly longer than the ones coming out from the back and I got them mixed up and later realized what I had done.  So just make sure you remember which screws come and go from where. (6) Finally do not get in a hurry.  As others have mentioned it is easy to break the bottom part of the existing drain.  So just go slow.
