Product review (3 stars): Arrived opened
Fits my "GE Profile Performance" fridge, previous filter FXRC Cartridge by Culligan.  This cartridge looks just like the FXRC.  Fortunately Amazon's return/replacement is efficient as the first filter arrived with the shrink wrap opened partway - the part over the attachment (like someone had opened it just enough to see if it would fit his fridge).  So back it went - thus the three stars.  Second one arrived properly sealed.  Installed without a problem, and no leaking (it's been in three days now).  I like this style over the kind you have to buy an attachment/adapter for, as the canister height controls where I can place my top shelf, and the taller the canister, the less space available to space out the other shelves.
