Product review (5 stars): Why pay more for the same quality and functionality?
While not LG-branded, this filter functions exactly like the filter that came with the fridge.  These do not leak or burst.  I bought a two-pack a year ago to make sure they would be OK and was frankly shocked at just how WELL they JUST WORK.  Works perfectly, lasts the full 300 gallons or 6 months.  Why pay more?
