Product review (5 stars): What your refrigerator don't know... won't hurt it...
PRO:

1.  Works like OEM.
2.  Easy install.
3.  Good for one year if you only use the ice maker.

CON:

1.  None

Other:

1.  RUN FIVE LARGE GLASSES OF WATER THROUGH THIS ASAP.
2.  Again, this will last a year, if you only use ice maker.  Just reset the filter notification on your appliance.
