Product review (5 stars): Replacement for LG Refrigerator
This is the second time I've bought the two pack.  I've used these for two years now and I can say I have had no problems.  I've actually used this for longer then 6 months per cartridge.  However, I have a whole house filtration.  Product fits right in and comes with silicone lubricant for orings.  No leaks and water tastes just like it should.  You can't beat the price and the performance continues to be fine.  I would highly recommend over the OEM version as there is no difference in my opinion.
