Product review (5 stars): Works as Advertised
We purchased this unit as a replacement water filter in our Samsung refrigerator.  The refrigerator itself was beginning to smell due to unknown causes, and so we decided to replace the water filter after cleaning everything else!

This unit took a little bit of time to install (5 or so minutes,) but that is more of Samsung's design of the refrigerator than it is the product itself.  So far it is still working great, the smell is gone, and the water tastes crisp and clean again.  I have now had it installed for a few months and I am incredibly happy.

All in all I would highly recommend.  The samsung replacements, as well as the replacements sold in Home Depot, are regularly more expensive and they don't do a better job than this unit in my opinion.
