Product review (5 stars): Worked well for me.
Had no issues with this product. I have seen others have trouble with ones they have ordered.
Some of the filters went right in and now they won't go in unless you turn off water. The pressure that builds up won't let you install until the water is turned off. This might have been case all along but I used to not have to turn off water and now I do. It took me along time to figure that out and want to save others from the hassle.
