Product review (5 stars): Works well after first few glasses drawn
The filter works fine on my Samsung fridge, though it would help if they had some installation instructions in the package.  On my fridge, the water leaked for a few seconds after drawing it, until a couple quarts had been drawn.  Then all was good.  If you're not aware of that, you might just assume it didn't work and return it.  Also, the first quart or two had noticeable charcoal residue from the filter, which cleared up after that.
