Product review (4 stars): Buy with confidence and save your cash
Great alternative to over-priced OEM parts!  The Waterdrop Plus filter cartridges are a perfect fit in my Samsung refrigerator and since the appliance is our of it's factory warranty, I have no issues using am alternative filter.  The filter appear to work exactly as advertised. I have only had it installed for a short time, but the water is absolutely clear and tastes great.
