Product review (5 stars): Great product for the price.
I was a little hesitate about ordering this product.  But, so far so good.  I haven't noticed anything different with the quality of the water or ice.  Seems to filter like the major brand I was buying, which cost $40 buck for one cartridge.  So far I am pleased with the quality and price.  If it fails to meet expectations in the near future, I will update my review.  Until then, I recommend this product.
