Product review (4 stars): If the original had never molded, I wouldn't be writing this...
The bellows has some design improvements over the original the most notable being that of a drainage port at the bottom.

The main reason I replaced the OEM bellows was because of mold. Installation was a PITA to put it succinctly. They should provide 4 of the spring holding pegs instead of 2, as it was it required all my limbs to install the bellows clamp spring, the holding pegs were almost useless. I had to use my left knee to supply tension on the spring to stretch it out with both hands in order to inch it around the bellows. Had I not needed my right leg to hold myself up, I would have involved it directly to the task of stretching out the spring as well lol. Whew. And only one or two slight cuts on my hands.

The door clamp was easy-peasy to install. I had zero leaks that others have complained of, maybe because I made sure to install properly and double/triple check my work before completing the task (hard to say, they may have had defective bellows).

My second biggest complaint is that the door now will not close properly every time and requires that you add pressure to the latch side when starting up the washer, otherwise you have a good chance that it will not latch properly and the buzzer will sound. I doubt much can be done to sort that and maybe over time the bellows will compress in certain areas to allow a positive latching every time w/o much effort.

Overall I'm glad I changed the bellows as the mold was atrocious, I also made sure to clean the tub rim and any areas that come in contact with the bellows with a bleach solution. I used a YouTube video as a guide and be forewarned at how simple they tend to make the task look.
