Product review (5 stars): Works as expected
This boot seal was easy to install.  We had a leak in our 9 year old washer, which was due to a tear in the boot seal. I first used $3 vulcanizing rubber cement (bike tire repair kit) to fix one of the tears, but found another tear where it bends that the cement wouldn't hold.

This went on in no time.  First, take off outer ring.  Then push torn seal into washer.  Find nut above seal and use a socket wrench to loosen then take off inner ring.  Put new seal on by doing everything in reverse.  Have some patience with the inner ring it needs to be worked on.  You'll be done in 15-20 minutes.
