Product review (5 stars): Other more expensive bellows out there, but this worked perfectly!
The original bellows got disgustingly moldy after about 10 years. It took a bit of looking to find the part number, as they had changed the part number and this was the matched compatible part. It was slightly different from the original though it works perfectly. There is a light port available if you cut the plug out. I did not have to do so as my machine foes not have a light. The "accordion" of this bellows is slightly different and wider from the original. The positive of this is that it dries out easier and is more open to clean. Unfortunately this also means small items (like booties or headbands) can get trapped in the bellows.
  The install of this was a pain in the butt! It does not stretch and it would be helpful to have a helper when installing. The included "clamps" do help but it takes a bit to get them wedged enough to hold the bellows as you work in on. There are a number of videos online that detail installing the bellows. It took me 45 minutes to change, probably 40 minutes of getting frustrated and 5 minutes after I had a turn of luck and the bellows stayed on. The bellows leaked a little bit (couple drops each wash) but it stopped after a couple high speed spins. I figure the spinning helped shake it into place and seal it completely.
