Product review (4 stars): Superman?
This looks different than the original seal.  Seems to be working fine, but was extremely difficulty to install.  The "sticks" that came with it were useless, I had to grab some small heavy duty clamps to get the first spring on there.  I'm no slouch, but did not have the physical strength to do it myself.  Overall it's great - if you have somebody strong enough available to stretch that spring on there.
