Product review (3 stars): Worked for me, after some modification.
Yeah, as other reviewers have pointed out, this may not have the right mounting bracket.  The one that arrived is the correct part number but doesn't match the one in the picture.  There's no easy way to swap the old bracket with the new so I had to bend/cut/file to get the unit to more or less fit.  As to function, great.  Solved my no water dispensing problem.  Fridge is: GE, Model: TFX25PRYFWW.  Old part number (WR57X119) has bracket as pictured in the amazon description.  This part, WR57X10051, is listed as replacement but it takes some extra time to get it fitted.

Also, the new unit has push-in fittings.  Old one has compression fittings.  Easy enough to cut off the old compression fittings, then the tube can just be pushed into the new fittings.  I had no problems with any leaks.

Anyway, it got the job done but it would be nice if it had been a proper drop-in replacement.  (Your experience may vary, depending on your precide fridge model.
