Product review (4 stars): Installed easily with no leaks
Item was shipped quickly.  Compared to OEM and looked very close.  Installed easily with no leaks.  OEM cartridge stated NSF 42 & 53 whereas this one was only marked NSF 42.  Was able to track down to http://www.cnfilter.net/productkey_en.aspx?key=RFC or http://www.globalsources.com/si/AS/Tianjin-Jinghai/6008825926150/pdtl/Refrigerator-Replacement-Filter/1108436052.htm
