Product review (2 stars): Would not purchase again
We purchased these expecting the same level of performance as the Samsung cartridges.  What we got were 3 filters that all performed poorly.  Water flow was substantially reduced compared with the OEM filters (it takes about twice as long to fill a cup of water now), and the refrigerator makes what can be described as a grinding or buzzing noise when the water is being dispensed.  I've tried all 3 of them, and have had the same problem with all 3.
