Product review (2 stars): Poor Quality Control
Ordered this item 6 months ago and it worked like a charm!  So I order the same filter (same model #) again, but this time it fails to install.  I looked at the "threads or teeth" near the top and they appear slightly different from the original filter ordered 6 months ago.  I send it back to Amazon and receive a replacement quickly.  But again it will not install.  Either Water Sentinel is is putting incorrect labels on its products or they've made a design error or production problem with this product.  Looks like I have no choice but to order a genuine "expensive" Samsung filter!
