Product review (5 stars): awesome product.  great vendor
I ordered two of these at incredible price, but because I needed immediate replacement I also went to my appliance parts store and bought one with a metal shim for 25 dollars.  Forums suggest there are problems with the metal version due to shaft stripping and/or fragments dropping into the motor housing.  So that expensive part was replaced with this identical replacement part as soon as arrived.  I would love to sell the metal one back and get my money back.  But these plastic ones from this vendor are keepers.  At this price I recommend buying 2 or more, you never know when these will no longer be available.  And apparently this part is pretty standard across multiple brands and machines so stash some and be a hero when your friends or relatives washer goes out.
In short replacement is a breeze. There is a great youtube video showing everything.  Just search it.
So Highly recommend this product and vendor.
Remember... plastic = original = good  metal = non-original = potential to be bad.
I would rather replace 10 of these then have to pay for a new motor. :)
