Product review (5 stars): Does what it is meant to do
We have tried other products in our GE refrigerator but something always went wrong..hard to install or to remove and sometimes leaks.  With this unit, that does not happen.  Installation is easy and the water tastes fine and keeps on tasting filtered for at least 6 months for our family.  It does cost more but over 6 months+  we think it is worth it.  The 3-pack also gives you some savings and should last for about 2 years.
