Product review (3 stars): Bought 'first' water filter replacement exactly what was on the brand new Frigidaire ref that came with it.
Ordered exact replacement filter unit when the warning light 'replace' came on.  Read and look carefully at the instruction diagram how to install the replacement unit.  It was a simple push forward to install the unit, tried it twice it did not work, tried it a third time, there is no way you can install the unit wrong side up, push the unit 'harder' did not work, re read the diagram again, nothing, inspected the replacement unit closely, the two prongs has a protective plastic cap/sleeve which I did not recognized, untill I looked at the old unit.  It would have been helpfull, if the install instruction states:  to remove the plastic sleeves before installing the unit.
