Product review (5 stars): Better Than OEM.
Considering that the OEM part lasted several years, I can see why these have a "lifetime" warranty. They're far beefier around the motor and transmission shafts than OEM and the fit is fairly tight (you'll want a mallet). The plastic also seems to be of higher quality; may be fiber-reinforced. Well worth the price, in any case. I bought an extra one but the steel parts of the washer will probably rust through before this thing breaks.
