Product review (1 stars): What's even worse is that service@ecolifefilter
Installed the Waterdrop WD-DA29-00020B into my Samsung RF4287HA, no water flow, removed and re-installed, still no water flow, re-installed original DA29-00020B, lots of water flow, repeated re-installation of the Waterdrop WD-DA29-00020B a few more times, still no water flow.  What's even worse is that service@ecolifefilter.com is the only customer service contact and they do not respond.  Avoid this product and brand completely.
