Product review (1 stars): Find a different brand!
One month after installing this water filter in my refrigerator and flushing with 4 gallons of water, my water still tastes like soap.  Unfiltered water from the tap taste fine, and the refrigerator water using the old brand of filter tasted fine.  Whatever change they made when they rebranded from Whirlpool to "Drop" has been for the worse.
