Product review (2 stars): Samsung French Doors Fridge Water Filter
At the time I purchased this, I bought this along with the actual Samsung water filter.  The taste of the water coming out of the filter tastes good, but the stream coming out is slower than when I originally bought my fridge.  On occasion the filter will rattle within the fridge which causes me to promptly release the water release.  Overall, it serves its purpose in filtering the water, but the water comes out slow and makes a lot of noise.  For the roughly $10 price difference, I think I will stick with the Samsung filter.  When you think about it, a filter will last you for many months.  Splitting that price difference over the course of the filter's life span really isn't that much more expensive.
