Product review (2 stars): More trouble than it is worth
Ever since installing this filter, the water dispenser runs for 5 or 6 seconds after the glass is disengaged from  the dispensing switch. Purging the water lines by running the dispenser continuously for 6 minutes, as suggested by some people online with similar problems, had no effect. Emails exchanged with the company helpline were useless - their representative just babbled nonsense as if meeting a word quota.
