Product review (2 stars): 2 out of 3 filters were bad.  Quality control issues are too big of a risk, despite bargain prices.
Bought a 3 pack a long time ago, the first filter install was great with only a slight difference compared to GE brand filters.  However, the issues started 6+ months in when I replaced the 1st filter with #2 of the 3 pack and the water flavor was horrible.  Instead of tasting like filtered water, I can only describe the the flavor as "filter soaked" water.  I did give the filter a chance by running through roughly 25-30 gallons, hoping the initial bad taste would pass but it never did.

I finally gave up and replaced #2 with #3 of the 3 pack hoping that the flavor issue was a rare oddity, especially given the numerous 5 star reviews of other customers.  Unfortunately, the #3 filtered water flavor was just as bad (but different in its own way).

At this point I can not recommend these as a viable alternative to the GE brand filters. What was initially thought to be a bargain purchase based on a price comparison to the GE brand filters and my positive experience with filter #1, quickly turned into a negative review when 2 of the 3 filters in the pack are terribly flawed by imparting a terrible taste onto the filtered water.
