Product review (2 stars): Not as good as the expensive LG brand
Is a bit smaller than the replacement.  Water tasted good right off, then the taste worsened a bit (but still much better than no filter, or the old one we were replacing.)

For the cost, I'm satisfied, and will buy again. I just can't justify over $50 for the normal LG brand.  I suggest you give it a try. Good value.

EDIT:
Review lowered from 4 stars to 2.  Within a month or so of installing the filter the water began to taste bad, and got progressively worse.  (as in worse than our normal tasting water).  I can only guess that the filter was beginning to 'grow' stuff inside it.  After replacing it with the basic LG filter, everything cleared up and the water tastes great (and has stayed tasting good).

I wanted to like this, but it just didn't work out for me.  I'll stick with the more expensive originals, for me, no money is ultimately saved by using this.
