Product review (1 stars): LEAKS!
This filter did not work in my Samsung RFG237AARS (23.7 cu ft French door model) purchased 12/2011.  The in-door water spigot ran-on and dripped.  Worse, the filter became pressurized like those old soda bottle and water rockets I had as a child!  When I removed the filter, it shot out from my hands and covered me and the inside of the fridge with water.  I was happy that it didn't break any of the glass shelves in the fridge!  I swapped A/B with the OEM filter and verified that the problem stayed with the filter.
