Product review (4 stars): Does the job
This unit is for the refrigerator that came with my house.  They seem to last about 4 to six months, and are on the expensive side.  Biggest complaint is that there is a bit of a funny taste when you first change the filter.  The instructions tell you to run several gallons through the filter before you begin drinking it.  In a fridge water dispenser, that can take a good while.
