Product review (5 stars): Great High Quality Deal!
VERY happy with these water purifiers for my LG fridge.  Wasn't sure what the quality would be given the low price (two for less than the price of one  OEM cartridge) - but I was pleasantly surprised.  The materials are of the same quality and the water is obviously being well filtered (we have heavy chlorine and minerals in our water).  Just a great deal all around!
