Product review (5 stars): Brand X... can be a good thing!
The filters I bought for my new Samsung refrigerator were not those suggested by Samsung.  They were, however, manufactured and presented as equivalents.  I find that to be true.  The price was much better and the service by the filter is as good as the Samsung filter that came with the appliance... all at a much better price.  I am set for replacements for the next two years for less than $100.  I am a happy camper.
