Product review (2 stars): The filter fit my LG refrigerator fine, and appeared to work well for 3-4 weeks
The filter fit my LG refrigerator fine, and appeared to work well for 3-4 weeks.  But, after that, the water flow quickly reduced to little more than a trickle.  Where I previously could fill a glass in 10-15 seconds, it began taking almost a minute. This was after less than a month of normal use.  Our last filter (LG brand) took 8+ months to even notice a reduction in flow at all.  I will not risk trying "Water Sentinel" again.
