Product review (3 stars): Sometimes it just doesn't work out.
I had previously rated these filters very well, but after my 4th or 5th one of these, I experienced a problem similar to that described by quite a few others.  I had a really great experience up until this last one, where it leaked like crazy.  Had to yank it out, send it back and temporarily replace it with the old one---I'll be going back to the OEM from LG.
