Product review (5 stars): Works perfectly and good water flow.
Got this to replace Samsung OEM model. Two Samsung filters received through Amazon clogged up within 3 weeks of use reducing water flow to a trickle so decided to try Water Sentinal filter. Filter is more narrow (probably due to use in multiple models of refrigerators) than Samsung, so fits in with a little space along sides. But locks in fine. I greased rubber ring with a touch of silicone spray to ensure good fit and no leaks. Water tastes clean and the water flow is great! So looks like I am switching permanently to this filter. It works on a different filtering system than the Samsung using a charcoal block. I do have to say that the original Samsung filter that came with my new refrigerator (the stainless Samsung RF4287HARS french door refrigerator; has extra drawer in the middle) lasted well over six months as opposed to the same filters bought through Amazon.
