Product review (1 stars): Defective
This item did not work properly when installed. Despite multiple attempts, and following the directions to the letter water would not pass through the filter. I probably received a defective product, which I understand is extremely difficult to avoid. It was a slight hassle to get a refund because I had to take the time to contact Amazon directly, the automated return process didn't work because this item is "nonreturnable" (for obvious sanitary reasons).
