Product review (5 stars): Quality replacement over OEM.
These water filters are an excellent deal over the OEM LG ones that cost a fortune.  These three packs extend that value even further.  Be sure and use the provided o-ring lubricant for an easy replacement next time.  If your fridge doesn't have a filter replacement light you can tell by the water flow slowing down that it is time for replacement.  My only complaint was that some boxes seem to have black flecks of something on the outside of the filter.  Nothing a quick wipe couldn't take care of.
