Product review (2 stars): our city water isn't really bad enough to "taste" a difference but overall
First off the capacity is wrong on the specs. It is a 200 gal not 300 as displayed. Also it went in but was difficult to install due to the fact that the stem between the o-rings is shorter than the LG it's supposed to be an exact match for. (Refer to corresponding picture - approx. .25" shorter than LG)  As far as quality goes, our city water isn't really bad enough to "taste" a difference but overall, unlikely I will purchase again
