Product review (3 stars): Works as long as you get it installed correctly (direction DOES matter).
Not quite a perfect fit for the filter it claims to replace.  When I first installed it, it leaked all over the place so I took it out.  I placed the old and new filters side-by-side and noticed that the holes in the new filter were only positioned as to allow the filter to be installed one and only one direction.  The original filter could be installed either way, but doing so with the new one causes leaks.
