Product review (1 stars): DO NOT BUY THESE!
These seemed to work at first but then after a few weeks it would let out some water and just stop.  It would have to "recharge" to let out more water, then stop.  Very frustrating.  And the refrigerator "change filter" light never came on.  So we are changing them about twice as often as we did with the name brand.
UPDATE:  DO NOT BUY THESE!  After the first one kept stopping the water flow, the next one lasted about 2 days and the next one about 2 hours!  Hope we have not permanently damaged our refrigerator.  There are so many counterfeits out there, we decided to just order from GE directly.
