Product review (3 stars): Taste of water was good right away
Taste of water was good right away. Unfortunately all flow stopped a few days after installing it. The seller was very good about helping resolve the problem and promptly refunded the purchase price when it was obvious there was a defect. I believe the defect was the placement of the ramps, molded into the filter, that open the inlet water valve on the mount in the refrigerator. This allowed the valve to close with the filter installed.
 I bought a factory GE filter from home depot and found it to give the water a distinct chemical taste, so in the future I will retry a Tier 1 filter from this vendor and see if the problems have been corrected.
