Product review (4 stars): So far, so good.
Seems exactly like the name brand so far.  Was easy to install but does not come with any instructions, so I peeled off the label of the original filter for future reference, otherwise I would rate this as a 5-star.  One can't know for sure about the purity of the filtered water, but the same goes for the name brand filter, so I'm trusting that it is working; the water tastes fine.
