Product review (5 stars): The "Waterdrop" was easy to install
We have a Maytag refrigerator.  I purchased the "Waterdrop" UKF8001 Replacement for Maytag UKF8001, 469005, 4396395 Refrigerator Water Filter.  The "Waterdrop" was easy to install.  Then we ran 2 gallons of water through the filter, and declared it ready for use.  The water is clear, the taste is good, and we are pleased.  Have set it up so we will receive a NEW "Waterdrop" every 5 months.  One less thing to worry about.
