Product review (1 stars): Bad Design.
Bad deisgn, did not work in whirlpool refrigerator that was orginally designed to use this filter. Like all its predecessor, within 3 days of installation the water flow starts to slow down from 11 seconds to 20 seconds to fill up 7 ounce cup. I thought they improved their design for better performance, I was wrong, they only changed the name and color of the filter.
