Product review (5 stars): That's a good thing. That was the problem with the one ...
Exact replacement.  The picture would lead you to believe that a section in the middle is see-through.  It isn't.  That's a good thing.  That was the problem with the one I had to replace as the plate underneath became detached.  Super glue only lasted a few loads.  Not surprising given I tried to glue plastic together inside a hot water pump.  But the replacement worked great.  You should transfer over the large seal / o-ring that goes around the outside of it.  Would be nice if it came with a new one pre-installed, but it doesn't.
