Product review (5 stars): Just get them!
Product may be just a tad bit smaller than the original OEM LG filter, but that is of no consequence.  It fits as it should and after running water through it (as you should) the water and ice taste great.  I believe people would be more likely to replace filters every six months as noted in the manual at this price point.  I plan on purchasing extras to have them on hand since they're just $10 instead of nearly $50 for the OEM filter.
