Product review (4 stars): NOT a factory part, but a comparable replacement
I had this professionally installed, which took the repair person 30 minutes.  It seemed flimsy out of the box, as others have mentioned, but is just as sturdy as the original once installed.  Understand, this is not a factory part, but it is comparable and if you want to save yourself about 50% in replacement costs, it does get the job done.  What I disliked about the product, or rather, the listing, is that it says "Whirlpool" above the product name, but then states that it is sold by a third party (somewhat misleading).  Also, it is somewhat different from the original Maytag part that came in the machine, having four holes at the bottom instead of five and the color is a different shade of gray.  There is a small amount of water that sits at the bottom of it after a wash, as others have mentioned as well.  The manufacturer does recommend wiping out the bellow after use to help avoid mold growth, which would solve this issue.  The repair man suggested not overloading the washer, leaving the door open, and running a dehumidifier to cut down on mold growth and avoid tearing the bellow.  Overall, I'm glad that I didn't pay an extra $60 when this part got the job done.
