Product review (4 stars): Directions were incorrect and misleading
These filters lose a star from me because the directions make a fairly simple task complicated, and made me think there was a problem when there wasn't. After removing the old filter, I tried to follow the directions, but they told me to twist the filter in the wrong direction, which got me no where. I finally tried twisting the opposite direction, and it turned securely into place, but when I tried to use the water, the filter made some loud noises. The directions said that if the filter makes noises, it's not installed correctly. However, after fiddling with it for a while, I decided that there was no other way to fit the filter in, and so chose to wait and see if the noise went away. By the next evening, the noise was gone, and now everything seems to be working like it should. I think I would have been better off in this case if I had lost the directions and just installed on my own.
