Product review (4 stars): Great for the one day that I owned it.
I just purchased this product for my GE refrigerator, and it installed easy.  I ran thru a couple of water to make sure it was working.  Water tasted fine. I gave that fridge away the day after this product was installed because I had already order a new Fridge so I can not comment on the longevity.  But it tasted fine when I had it.
