Product review (2 stars): Not cost effective for what it does
Not usually one to complain about price in a review because I've always thought, "if you don't like the price, then why'd you buy it?".  I mean, it's not like you bought it and then found out later how much it cost, right?
  Well, I bought this because I thought it was doing more than it does.  Recently I bought a total dissolved solids (TDS) meter and tested our water before and after the filter a few days after putting a new one in.  Maybe I was expecting too much, but knocking the TDS down from 121 city water to 86 filtered was underwhelming.  Nope, did not feel whelmed in the least.
  For the price of a year's supply of these, you can get an external filter that will knock TDS down to single digits.  And if all you're using it for is the fridge, like this is for, then it'll last you a lot longer.  This is way overpriced for what it does and I've just ordered a RO/DI system so I don't have to buy another.
