Product review (5 stars): No need for the big box store - WORKS GREAT!
After vacationing in Iceland (where the tap water is AMAZING) - my wife and I came home to the truth that our tap water tasted like CRAP. We were totally complacent with it until our trip, but knew we needed to do something. Our 2006 model LG fridge had a spot for a filter, and simply a flow-through attachment placed where a filter should've been. This filter was plug and play and after a minute of running the water through the fridge we noticed a pleasant difference in taste.

Don't throw $50 at the big box store on these. This filter does the job wonderfully, at a fraction of the cost. I will be buying more when we need them.
