Product review (2 stars): Don't buy. Problems.
The price looked great so, to save  money, I bought them.  Unfortunately, they don't work because they don't properly fit.  When getting water, it will start making a tremendous pounding sound then stop then start again.  After a while, even when not getting water, it will cause a loud pounding noise. I checked in case it was something else in the refrigerator but found the noise was coming from where the filter was installed.  When I pushed the filter in and wiggled it, the noise would lessen a bit, temporarily, then start up again.  I'm returning them to Amazon.  .
