Product review (1 stars): Very limited life and adds particles to the water.
Very disappointed with this filter.  I should have known it was a cheap Chinese knock-off when I saw the price, but it was too tempting not to try.  Like some other buyers who gave this product a one star rating, I was initially satisfied with the quality of the water filter.  However, after about one month, not only did the water start to taste just like unfiltered tap water, but I started to see small black particles in each glass of water.

Given the fact that you have to look real hard to find Made in China on this product, it appears that they know what an awful knock-off product they've made with this filter. In retrospect, this is not the type of product one should buy based on price; my family drinks filtered water to ensure that the many contaminants of tap water are mostly filtered out. In the case of this filter, not only did it 'filter' the water for a short amount of time, but it also added some contaminants of its own after a month or so.  I do not recommend this product.  Spend the extra money for the brand name filter.  That's what I plan to do after posting this.
