Product review (4 stars): I was very hesitant to purchase these filters after purchasing ...
Update:  I removed a star as I later realized that the taste of the water doesn't really compare to the original LG LT800p filter.  Ice doesn't taste as good and if you let the water sit in your cup for a while, you get a taste that the LG filters don't have.  After only using the filter for 3 months, water taste is worse.  However, I only removed one star because the price of the LT800p filters are so expensive now that it is hard to justify paying so much more for a slight increase in taste quality.  Because the Waterdrop filters are so much cheaper, you can just replace them more frequently and still save money.  I will likely still continue to purchase these filters.

Original post:  I was very hesitant to purchase these filters after purchasing the LG filters for so long, but the price of the LG filter almost doubled since my last purchase.  I have a very sensitive sense of taste and smell.  I am able to notice a slight difference in the taste of the water between this filter and the LG filter, but there is no difference in the smell of the water.  The difference in taste is so minor that it is not enough for me to spend five times as much to get the LG filter.  These filters fit perfectly into my LG refrigerator.  I will definitely be purchasing these filters again.
